iso: audit-sweep UID, bakery update, lockfile, welcome, autostart

Resolve MAIN_USER after deleting liveuser so Snapper and skel target the
installed account. Wrap bakery update with sudo -n/pkexec for /usr/local.
Pin bakery and bread-theme 0.7.4; require bread-emit and bread-module-host.
Make Calamares internet check non-blocking against breadway.dev. Autostart
breadlock listen. Smoke avahi-daemon.socket to match post-install.

+curl -fsSIL https://dl.breadway.dev/arch/x86_64/breadway.db.sig
+```
+
+Both must be HTTP 200. A 404 on `breadway.db.sig` means do **not** flip
+`SigLevel` to `Required`.
+
+Import `KEYS.asc` and check the detached signatures:

+```sh
+gpg --import KEYS.asc

-# upload "$PKG" and "${PKG}.sig" to dl.breadway.dev/arch/x86_64/
-# then repo-add -s as above

-
-Keep publishing to Forgejo until installs have been switched. The ISO
-section stays `SigLevel = Never` until the signed tree is live.
+still `makepkg`s and PUTs the archive at Forgejo's registry. That path
+stays; Never installs keep working. The signed tree is rebuilt by the bos
+workflow above (registry fetch + sign + `repo-add -s`), not by writing
+`/srv` from breadlock's container.
 
 ## After the signed repo exists
 
+Only after `https://dl.breadway.dev/arch/x86_64/breadway.db.sig` HEADs 200
+and the verify commands above succeed:
+
 1. Import `KEYS.asc` into the ISO keyring (`pacman-key --add` + `--lsign-key`).
 2. Point `[breadway]` `Server` at `https://dl.breadway.dev/arch/$arch`.
 3. Only then flip that section to `SigLevel = Required`.

-`iso/pacman.conf` and `iso/airootfs/etc/pacman.conf`.
