feat(installer): Skip login manager when unl0kr handles the passphrase

unl0kr already prompts for the LUKS passphrase on screen, so a login
manager on top of it would be a second prompt. The login screen now only
collects a fallback (none/greetd/sddm/gdm) when unl0kr is selected;
resolve_login_manager applies it only when install_unl0kr falls back to
the systemd initramfs, and the summary shows both states.

Also ships /etc/unl0kr.conf (breezy-dark) plus the empty
/usr/share/unl0kr/unl0kr.conf the package omits so unl0kr stops warning
about an unparseable config, and pins Hyprland in the user's
AccountsService record so gdm autologin does not fall back to
gnome.desktop.

+## alvin-install (installer inside the ISO)
+
+Source: `airootfs/usr/local/bin/alvin-install` (~1,880 lines, **no `.sh` extension**).
+The airootfs overlay ships it as `/usr/local/bin/alvin-install` (mode `0755` forced in
+`profiledef.sh` `file_permissions`), and `/etc/motd` advertises it on the live medium.
+
+- **Invoke**: as root from the live session. Hard requirements: `gum` and UEFI —
+  `check_prereqs` exits if `/sys/firmware/efi` is missing. Log: `/var/log/alvin-install.log`
+  (copied into the target at the end; `ERR` trap prints the failing line).
+- **Structure**: `main()` runs 16 `screen_*` TUI functions (collect answers: welcome, keymap,
+  network, disk, luks, unl0kr, filesystem, username, password, hostname, git, timezone,
+  locale, login manager, sshd, summary) then a fixed order of `install_*` steps
+  (partition → LUKS → format/mount → pacstrap → fstab → repos → timezone → locale →
+  hostname → network → sshd → user → git/SSH → end-4 dots → mkinitcpio → bootloader →
+  TPM/unl0kr → login manager (none if unl0kr succeeded; with unl0kr selected the login screen only asks for a fallback) → autologin → update (reflector + keyrings + `pacman -Syu`, warn-only) → cleanup). Screens and install steps are
+  independent — edit one without
+  touching the other. An `EXIT` trap unmounts `$TARGET` and closes `cryptroot` on any exit.
+- **Package list**: `install_pacstrap` builds the *installed* system's list from the medium's
+  `/run/archiso/bootmnt/arch/pkglist.x86_64.txt` (i.e. `pacman -Q` of the live ISO), so
+  `packages.x86_64` changes flow into installed systems. It drops `PKGS_EXCLUDE`
+  (`archiso mkinitcpio-archiso mkinitcpio-nfs-utils syslinux memtest86+`) plus names not
+  resolvable in the live repos, then always appends hardcoded essentials
+  (`base linux linux-firmware linux-cachyos networkmanager grub efibootmgr sudo git …`).
+- **Linting**: CI's shellcheck step picks it up by its bash shebang. Locally:
+  `shellcheck -x -s bash airootfs/usr/local/bin/alvin-install`
+- end-4 quirks (`--skip-alldeps`, `yes i`, end4-pC re-copy) are in [Gotchas](#gotchas) below.

 ## Gotchas
 
-- The profile root is the **repo root** (not a `releng/` subdirectory). The CI build-iso workflow uses `mkarchiso -v -w work -o out/ releng` but this is a naming convention — the actual profile files live at the repo root.
+- The profile root is the **repo root** (not a `releng/` subdirectory). CI builds with `mkarchiso -v -w "$PWD/work" -o "$PWD/out" -- "$PWD"` (`.gitea/workflows/build-iso.yaml`), and the local build command above does the same — never pass a `releng` path.
 - `customize_airootfs.sh` clones git repos (oh-my-zsh, lazy.nvim, plugins, end-4 dots) into `/etc/skel` and `/opt` during the ISO build. These require network access at build time but make the live ISO work offline.
 - `customize_airootfs.sh` runs `./setup install-deps -f -s --skip-plasmaintg` as the throwaway user `ii-builder` (end-4's scripts refuse to run as root) and aborts the build if it fails. `--skip-plasmaintg` is deliberate: that optional Firefox widget pulls 410 packages / 526 MiB of KDE.
-- The `[local-aur]` repo path in `pacman.conf` (`file:///home/alvin/alvinarch/localrepo`) is for local builds only. The CI does not use this path.
+- The `[local-aur]` repo path in `pacman.conf` (`file:///home/alvin/AlvinArch/localrepo`) is for local builds only. The CI does not use this path.
 - The **image** ships its own `[local-aur]` at `file:///opt/localrepo` (see `.live-pacman.conf`). It holds `localrepo/` (copied by CI/`update.sh`) plus everything `install-deps` built. pacstrap runs without `-P`, so the target keeps the stock `/etc/pacman.conf`; `alvin-install` strips `[local-aur]` from it anyway as a safety net, because `/opt/localrepo` exists only on the medium.
 - `alvin-install` runs end-4 with `--skip-alldeps` — dependencies must come from the ISO. It feeds `yes i` to end-4's failure prompt: inside the installer chroot the medium's `/run` is bind-mounted in, so end-4's `systemctl --machine=…@.host --user enable … --now` lines can never work (and `--now` would start services on the live medium). `install_end4_dots` re-applies the enable-only part (bluetooth, ydotool, i2c module) outside the chroot and reports every step end-4 had to skip. If the end-4 step reports "incomplete", check that `hyprctl`/`quickshell`/the venv were resolvable (harvest) before re-running anything.
 - `/etc/skel/.cache/uv` + `/etc/skel/.local/share/uv/python` are pre-warmed by the build (~460 MB: CPython 3.12 and the pinned wheel cache) so end-4's `uv venv`/`uv pip install` at install time needs no network.
 - **end4-pC** (`pctrade/end4-pC`) is the default quickshell config: cloned into `/etc/skel/.config/quickshell/end4-pC` at build time, selected by patching `hl.env("qsConfig", "ii")` → `"end4-pC"` in the **staged** `/opt/dots-hyprland/dots/.config/hypr/hyprland/variables.lua` (there is no `hypr/hyprland/` in this repo — `./setup install` copies it to the installed system). `alvin-install` re-copies end4-pC into the user's home *after* `./setup install`, because end-4's installer `rsync --delete`s all of `~/.config/quickshell`.
 - `airootfs/etc/skel/.config/illogical-impulse/presets/` carries the user's presets (`Laptop.json`, `Personal-Performance.json`, `Personal-Performance.zip`). They embed `/home/alvin/...` paths, so wallpapers/screenshots need fixing up after install.
 - End-4 metapackages are built from `localrepo/end4-pkgbuilds/` (quickshell-git, bibata-modern-classic-bin, microtex-git).
+- **quickshell pin / Qt 6.12**: end-4 pins quickshell to `41651d7` (Sep 25), which predates upstream fix `5d5d498` (Oct 3, *"use MOC includes instead of opaque pointer definitions — … Qt 6.12 compatibility"*). Arch shipped qt6 6.12.0 on Oct 8 and the old pin died with `Meta Types must be fully defined` in the moc build of quickshell-hyprland-ipc (failed CI run 137). `customize_airootfs.sh` therefore rewrites end-4's `_commit` to `11ca60be` after cloning — but **only** while it still matches `^_commit='41651d7`, so once end-4 bumps their own pin the guard goes inert and theirs wins. `localrepo/check-quickshell-pin.sh` (weekly `pin-check.yaml` job) fails CI if either pin goes stale or loses the fix; it warns instead of failing when end-4's known-stale pin is covered by the override.
+- **MicroTeX flags**: the image's `makepkg.conf` is CachyOS's (`-march=native -O3`, LTO). GCC 16.2 hit an internal compiler error (segfault) on MicroTeX's `gtkmm_main.cpp` with it (failed CI run 155; not reproducible locally), so `customize_airootfs.sh` patches end-4's `illogical-impulse-microtex-git` PKGBUILD to `options=(!lto)` + `-O2` (our `localrepo/end4-pkgbuilds/microtex-git` carries the same).
+- **CAP_SETFCAP on the runner**: without it pacstrap drops `security.capability` xattrs (newuidmap/newgidmap, snap-confine, dumpcap, kwin_wayland, ...) from the live ISO with only a warning. `build-iso.yaml` fails the job early if the runner lacks it — fix the runner, don't remove the check.
+- **yay SIGSEGV on exit**: yay 13 (libalpm via purego/`dyalpm`) can segfault in `alpm_release()` *after* a finished transaction (failed CI run at end-4's `illogical-impulse-kde` step), which aborted `install-deps`. `customize_airootfs.sh` puts a temporary `yay` shim first on the builder's `PATH`: a failed plain `yay -S <pkgs>` counts as success only if `pacman -T` confirms every target is installed (it logs `[yay-shim]`). Every other failure keeps yay's exit code.
+- **gvfs / dead `~/.gvfs`**: `install_end4_dots` replays end-4's gsettings writes via `dbus-run-session` as the target user. A session bus D-Bus-activates gvfsd → gvfsd-fuse mounts `~/.gvfs` and dies with the bus, leaving a dead FUSE mount that root can't stat, so the home's catch-all `chown -R` failed (`cannot access '/mnt/home/<user>/.gvfs': Permission denied`) and aborted the install before the bootloader. The replay therefore runs with `GIO_USE_VFS=local GVFS_DISABLE_FUSE=1`, and the function unmounts anything mounted under the home before that chown — keep both.
+- mono's `cert-sync` runs before `ca-certificates.crt` exists during pacstrap, so `customize_airootfs.sh` (live) and `install_pacstrap` (target) re-run it.
+- `/etc/skel/.zshrc` is owned by `grml-zsh-config`, so ours is staged as `airootfs/root/.zshrc-skel` and installed by `customize_airootfs.sh` after pacstrap — never add files under `airootfs/` at paths a package owns, or pacstrap aborts with "exists in filesystem".
 - `packages.x86_64` is sorted alphabetically. Keep it sorted when adding/removing entries.
 - `airootfs/opt/localrepo/` is a build artifact (gitignored) — never commit it.
-- **Build stamp flow**: `profiledef.sh` (sourced by mkarchiso) stages the gitignored `airootfs/root/.iso-build-stamp` when a `.git` dir exists **or** `CI`/`GITEA_ACTIONS` is set — line reads `AlvinArch build <date> | commit <date> | <4-char hash>` (falls back to `commit unknown` if `git -c safe.directory` can't read the repo; without `.git`/CI no file is staged). `customize_airootfs.sh` installs it as `/etc/alvin-build-stamp` on the live medium, and `alvin-install`'s `install_motd` copies the live `/etc/motd` banner to the target and appends the stamp. If the medium has no stamp, the installed system gets no motd from us.

The installed system's motd is never touched by us — `alvin-install` has no motd step (an earlier `install_motd` that copied the banner + stamp into the target was removed on purpose).

+## Automated Installer (alvin-install)
+
+The ISO ships an interactive installer at `/usr/local/bin/alvin-install` (source:
+`airootfs/usr/local/bin/alvin-install`, ~1,880 lines of bash; the live `/etc/motd`
+advertises it). It partitions, encrypts, installs, and fully configures a system —
+including the end-4 dotfiles — without network access to this repo.
+
+### Running it
+
+```bash
+alvin-install   # as root on the live medium (root autologins on tty1)
+```
+
+Requirements: **UEFI boot** (it exits if `/sys/firmware/efi` is missing — BIOS/CSM
+is not supported by the installer) and `gum`. A network connection is required and
+verified by pinging `archlinux.org` before any disk is touched; the network screen
+can open `nmtui` for WiFi. Every step is logged to `/var/log/alvin-install.log`,
+which is copied into the installed system.
+
+### What it asks (gum TUI screens)
+
+Keymap → network → target disk (the live USB is hidden from the list) → LUKS
+encryption (optional; **the LUKS passphrase is the same as your login password**)
+→ experimental unl0kr touchscreen unlock → filesystem (`ext4`/`btrfs`) →
+username/password/hostname → git identity + GitHub username (both optional) →
+timezone/locale → login manager → SSH server (enabled by default) → summary.
+
+### What it does
+
+1. GPT partitioning (1 GiB ESP) on the chosen disk, optional LUKS2 on the rest,
+   format + mount at `/mnt`
+2. `pacstrap` with the package list derived from the medium's
+   `pkglist.x86_64.txt` (`pacman -Q` of the live ISO) — `archiso`, `syslinux`,
+   `memtest86+` etc. are dropped, hardcoded essentials (kernel, GRUB,
+   NetworkManager, cryptsetup, microcode) always appended
+3. User account, sudo, git config, GitHub SSH keys (`ssh-import-id`, falling
+   back to `github.com/<user>.keys`)
+4. end-4 dotfiles from the staged `/opt/dots-hyprland` via
+   `./setup install -f -s --skip-alldeps`
+5. Initramfs in one of two modes: **Mode A** — systemd initramfs + `sd-encrypt`
+   (default); **Mode B** — busybox hooks + unl0kr touchscreen unlock
+   (experimental, mutually exclusive with TPM2; falls back to Mode A on failure)
+6. Optional **TPM2 auto-unlock** (`systemd-cryptenroll`, PCR 0+7; passphrase
+   slot kept as fallback; warns if Secure Boot is off)
+7. GRUB (UEFI, boot entry `ALVIN`), login manager — `none` (plain tty, Hyprland
+   autostarts), `greetd`+tuigreet, `sddm`, or `gdm` — falls back to `none` only
+   if the **package** can't be resolved/installed; a failed `systemctl enable`
+   keeps `getty@tty1` as the login path (the summary still reports the chosen
+   manager). Optional autologin (forced off when TPM2 is enrolled), and sshd
+   enabled at boot when selected (default: on) — Arch's stock config allows
+   **password login with the same password as LUKS**, so only accept the default
+   on networks you trust (or harden `sshd_config` afterwards). The final banner
+   reports whether the enable actually succeeded, not just what was selected
+
+On failure an `EXIT` trap unmounts `/mnt` and closes the `cryptroot` mapping, so
+re-running is safe. If the end-4 step reports "incomplete", see the repository's
+`AGENTS.md` Gotchas for the chroot/systemd limitations that cause it.

+### zsh-autocomplete partial-load error
+
+Symptom:
+
+```
+_autocomplete__history_lines: function not defined
+_autocomplete__unambiguous: function not defined
+```
+
+Cause: zsh-autocomplete was loaded after `compinit` (e.g. via oh-my-zsh
+`plugins=(...)`), a stale completion dump, or a conflict with
+zsh-autosuggestions / zsh-history-substring-search. On this ISO `compinit`
+always runs first: grml-zsh-config's global `/etc/zsh/zshrc` calls it
+unconditionally before `~/.zshrc` is read.
+
+The shipped `~/.zshrc` leaves zsh-autocomplete out of `plugins=(...)`. The
+plugin stays cloned at `~/.oh-my-zsh/custom/plugins/zsh-autocomplete/`
+either way, just disabled by default.
+
+**Fix: drop autocomplete (recommended)**
+
+```bash
+# 1. Edit ~/.zshrc, remove this line from plugins=(...):
+#    zsh-autocomplete
+
+# 2. Clear stale dumps (bash avoids zsh's nomatch abort on the glob):
+bash -c 'rm -f ~/.zcompdump* ~/.cache/zsh/zcompdump*'
+
+# 3. Restart the shell and verify:
+exec zsh
+typeset -f _autocomplete__history_lines >/dev/null && echo "still loaded" || echo "clean"
+```
+
+**Fix: keep autocomplete instead**
+
+```bash
+# 1. Remove zsh-autocomplete, zsh-autosuggestions and
+#    zsh-history-substring-search from plugins=(...) in ~/.zshrc.
+
+# 2. Stop the global compinit. `skip_global_compinit=1` in ~/.zshenv does
+#    NOT work here (that is a Debian/Ubuntu /etc/zsh/zshrc convention; grml
+#    ignores it), so remove the package that ships the global zshrc:
+sudo pacman -R grml-zsh-config
+
+# 3. At the very top of ~/.zshrc, before oh-my-zsh is sourced:
+source ~/.oh-my-zsh/custom/plugins/zsh-autocomplete/zsh-autocomplete.plugin.zsh
+
+# 4. Clear dumps as above, then: exec zsh
