Claude b0b558f015 Migrate Complete Uninstall, composed from each addon's own uninstall helper; bump to v2.12.0
New menus/complete_uninstall.sh (Core Settings), the last of the
"destructive trio". Rather than re-implementing every addon's teardown
a second time (the legacy shape), it composes the *_do_uninstall
helpers each addon already has - if an addon's removal logic changes,
Complete Uninstall picks it up automatically.

Every addon menu with an uninstall action (CUPS, VNC, WireGuard,
Tailscale, Netbird, LMS, Squeezelite, Asterisk Intercom) plus
power_schedule's "remove all schedules" and Emergency Hotspot's disable
action were each split into a confirm-and-call wrapper (unchanged from
the user's perspective) and a silent do-the-removal helper that both
the wrapper and Complete Uninstall call.

Bug fix found while composing these: several *_do_uninstall helpers
(CUPS's apt autoremove/apt clean, VNC/WireGuard/Tailscale/Netbird's apt
remove) had a bare, unguarded apt call as their second-to-last
statement. Previously this only risked aborting that one menu action if
the package was already gone. Composed together as sequential calls
inside Complete Uninstall, the same failure would have silently
truncated the entire uninstall sequence partway through. Guarded all of
them with `|| true`.

Non-addon teardown (kiosk user/files, Node.js, LightDM/Openbox,
remaining systemd units/scripts, polkit rules, re-enabling virtual
consoles, final package cleanup) stays inline in
menus/complete_uninstall.sh, since no single addon owns those paths.

Upgrade and Full Reinstall stay in ubuntu-based-kiosk.sh only - both
are coupled to its own heredoc self-extraction of main.js/preload.js/
etc, which has no modular equivalent yet.

Full command-level stubbed test suite exercising the full 12-step
teardown, confirmation-text validation, and reboot prompt. Full
19-suite regression + real end-to-end menu navigation via install.sh
all pass.

Claude 1b16bcf3ee Migrate CUPS Printing addon; restructure install.sh into Core Settings/Addons/Advanced; bump to v2.5.0
First Addon migrated: menus/addon_cups.sh (install, reconfigure for
network access, complete uninstall/purge). Different risk profile from
everything migrated so far - it genuinely mutates real system state
(apt install/remove --purge, /etc/cups, ufw) at fixed paths CUPS itself
doesn't let us relocate, unlike the systemd/cron/bin paths this project
already controls via $SYSTEMD_DIR etc. Only the polkit rule's directory
is parameterized ($POLKIT_DIR, lib/config.sh, since that one is ours to
place); everything else gets full command-level `sudo` stubbing in
every test - there is no scratch equivalent for a real apt-managed
subsystem's own file layout. Also added $BUILD_USER (the admin account
actually running the tool, as opposed to $KIOSK_USER) since CUPS needs
to grant it lpadmin group membership.

Restructured install.sh's top-level menu into Core Settings / Addons /
Advanced (matching the legacy tool) instead of one flat list, now that
Addons exists as its own category - cheap to do with one item in it,
much more annoying to retrofit once the flat list has fifteen.

Two bugs caught and fixed before they shipped:

- A "wait for CUPS to start" retry loop used a bare `cmd1 && cmd2 &&
  break` as its body while "simplifying" the legacy script's `if cmd1
  && cmd2; then break; fi`. Being inside a loop doesn't protect a bare
  &&/|| list from set -e - only if/while/until conditions and the
  protected side of &&/|| do that - so the first command failing on an
  early iteration (near-certain right after a fresh install, before
  CUPS has actually started) would have crashed the entire session.
  Restored the `if` form; noted the lesson in the file's own header
  comment since it's a general trap, not CUPS-specific.

- Resolved real uncertainty, rather than assuming: how far does
  run_menu's `handler || true` guard (v2.1.0) actually protect? Wrote a
  minimal isolated test (a bare `false` three function calls deep,
  called via `outer || true` at the top) and confirmed bash's errexit
  exemption for the left side of `||` covers the *entire* evaluation,
  arbitrarily deep through function calls - not just the immediately
  invoked function. So the session-crash risk this project has been
  chasing since v2.1.0 is already covered end-to-end by that one fix.
  Per-statement guards (`|| true`, explicit `if`) still earn their keep
  for a different reason: without them a deep failure bubbles silently
  past the menu actually responsible for it to wherever the nearest
  `|| true` happens to sit, which can be several menu levels above
  where the user actually was - not a crash, but a confusing jump.

Verified:
- Full regression: re-ran every existing scratch-config/stub test suite
  after the lib/config.sh change (new $BUILD_USER/$POLKIT_DIR) and
  after the install.sh restructuring - all still clean.
- New scratch/stub test for addon_cups.sh: full state-machine coverage
  (not installed -> decline -> install -> running -> reconfigure ->
  stopped -> start -> uninstall decline -> uninstall confirm -> not
  installed again) with every `sudo` call intercepted and only `rm`
  targeting the scratch $POLKIT_DIR ever actually executed; confirmed
  the polkit rule's content and that declining install makes zero sudo
  calls. Added both apt-failure paths (update fails, install fails)
  and confirmed the tool reports clearly and returns to the menu
  instead of dying, exercising the exact bug class just fixed.
- End-to-end: ran the real install.sh as a genuine non-root, non-
  "kiosk" user through the full new three-level structure - Core
  Settings -> Sites -> back -> back, Addons -> CUPS -> declined install
  (using this container's real, unstubbed dpkg check, correctly
  reporting "not installed" and making no apt/systemctl calls) -> back
  -> back, Advanced -> Diagnostics -> System status -> back -> back ->
  Exit. Zero invalid-choice errors, clean exit code 0 throughout.
