Firewall's fetch_status() discarded stderr/exit code on failure, so a
failed pkexec call (e.g. no polkit agent in the session) left the page
silently stuck on "Status not loaded" with no indication anything went
wrong. Now surfaces the actual failure reason, and attaches the
previously-invisible per-action log buffer to a visible TextView
(matching the Packages page's existing pattern).
Snapshots' "No snapshots yet" empty state was shown identically whether
snapper was genuinely unconfigured or the user just lacked permissions
(a "No permissions." stderr) -- now distinguishes the two.
Split out of the bos repo so a bos-settings release no longer requires a
BOS ISO release (and vice versa) — CI here publishes straight to the
[breadway] pacman repo on tag push, independent of bos's own release cadence.
Also adds real GUI editors for the Hyprland JSON config surfaces bos gained
recently (hypr/settings.json, hypr/monitors.json, hypr/autostart.json):
- Appearance panel: gaps, borders (with a real color picker), blur, shadow,
tiling layout, and basic input settings.
- Display panel: a monitor-rule list editor alongside the existing live
connected-monitor readout.
- Startup Apps panel: toggle/edit/add/remove the extra autostart commands.
- --page argv support for deep-linking (breadhelp's guides can now open
bos-settings straight to a specific page).
- Fixed a stale "View keybinds cheat sheet" button pointing at a file
deleted when breadhelp replaced bos-keybinds/bos-welcome.
