alvinlollo 23915c301a Strict mode from the start, contextual errors, non-zero exit in installbeta.sh 
- set -Eeuo pipefail at the top (was only enabled after the menu, so
  package installs and shelly bootstrap ran unchecked); preamble audited
  for guarded vs unguarded commands ([ -t 1 ] && ... became an if, clear
  is now 'clear || true')
- error_handler now reports exit status, line number and the failing
  command, and the ERR trap is installed after strict mode so preamble
  failures abort instead of printing a message and continuing
- exit 1 when any step was recorded as failed (was: always exit 0)
- single STAMP shared by LOG and REPORT; both created via mktemp
  (predictable /tmp log names + tee -a was the same symlink class)
- local script/config fallbacks resolved via BASH_SOURCE (SCRIPT_DIR),
  not the caller's CWD; falls back to remote fetch when piped
- $? captured via rc=$? inside each failure branch (idempotent under
  reordering) for all record_failure call sites
- ${1:-} for the flag check, ${SHELL:-} in the fish detection,
  tty-guarded fish warning prompt
