- breadbox: was 'cloud sync daemon + file browser'; it's actually a GTK4
fuzzy app launcher; breadbox-sync resolves icons, not cloud data
- breadcrumbs: was 'network information CLI'; it's a profile-aware Wi-Fi
state machine with Tailscale integration and a watch daemon
- breadpad: was 'scratchpad / quick-note app'; call out AI classification,
reminders, recurrence, and the breadman viewer
- system deps: add gtk4-layer-shell for breadbox and breadpad (both use
layer-shell windows); drop spurious 'dbus' from breadbox
