New OFFLINE MODE group above the cache group on the Offline settings page:
read-only tri-state status row (online / no connection / offline mode
enabled, with captive-portal hint) plus an honest Check now that forces an
actor re-probe; Enable Offline Mode toggle driving the shared engine (issue
#279 stream_first_track snapshot/restore included, Playback panel re-synced
after); Show Network Folder Content toggle mounted only while induced
offline is on. Deliberate deviations from Tauri per the approved spec: no
probe gate on disable, no dead cast/scrobbling toggles.
