feat(sync): drop quiescence guard in favor of live WAL-based sync

- Remove `canAutoSync` dep from scheduler; auto-sync now runs during playback/stats
- Sync window always passes `--force`; WAL snapshots and transactional merges handle concurrent writers
- Update docs to clarify live vs cold-start sync modes

type: added
area: sync
- Added a sync window (`subminer sync --ui`, or **Sync Stats & History** in the tray menu) for cross-machine immersion sync: saved devices with per-host direction (two-way/push/pull) and remove, one-click sync with live stage-by-stage progress and separate merge summaries for this machine and the remote device, connection testing for first-time setup, cancellable runs with a one-click `--force` retry when the running-app guard trips, and manual database snapshots (create/merge/reveal/delete, stored in `/tmp/subminer-db-snapshots/` by default). Hosts with auto-sync enabled are synced in the background on a configurable interval while no mpv session or stats server is writing the database, with results reported as overlay notifications. Hosts synced from the CLI are remembered in `<config dir>/sync-hosts.json` and show up in the window automatically. `subminer sync --ui` launches silently in the background and returns the shell immediately; closing that standalone Sync window shuts down the app.

Live sync uses a consistent WAL snapshot and transactional merge, and excludes unfinished sessions until a later sync sees them finalized. Hosts with auto-sync enabled are synced in the background on a configurable interval, including during playback, with results reported as overlay notifications. Hosts synced from the CLI are remembered in `<config dir>/sync-hosts.json` and show up in the window automatically. `subminer sync --ui` launches silently in the background and returns the shell immediately; closing that standalone Sync window shuts down the app.
- Added `subminer sync <host> --check` to test the SSH connection and remote launcher availability without syncing, using bounded noninteractive probes and settling when the check process exits even if an inherited output pipe remains open, without dropping terminal progress that races process exit. Linux AppImage sync commands clear inherited GUI startup argument transport before launching the bundled engine, then exit directly, so sync window checks and remote snapshots never initialize the GUI or require a display server. Added `subminer sync --json` for machine-readable NDJSON progress output (the protocol the sync window consumes).
