docs(sync): remote machine only needs the app - checklist, docs, changelog

Sync window drops the launcher-missing warning (self-spawn always works),
the setup checklist explains automatic remote discovery (SubMiner on
PATH, macOS /Applications, or the optional launcher), and the remote
resolver gains tests for app-binary fallback and --remote-cmd probing.

The command-line launcher is optional on both sides: the app itself answers sync commands (`SubMiner --sync-cli sync ...`), the sync window runs the engine in-app, and the remote side is found automatically whether it has the launcher or just the app.

 ### Sync window
 
 `subminer sync --ui` (or **Sync Stats & History** in the tray menu) opens a dedicated window for the same engine:
 
 - **Devices** — saved hosts with a per-host direction (two-way / push / pull), an auto-sync toggle, last-sync status, and one-click **Sync now** / **Test** / **Remove**. Hosts synced from the command line appear here automatically.

 - **Activity** — live stage-by-stage progress, remote output, and a merge summary (sessions, words, kanji, rollups) when a run finishes. Runs can be cancelled, and guard failures offer a one-click `--force` retry.
 - **Snapshots** — create manual database snapshots (stored in `/tmp/subminer-db-snapshots/` by default), merge a snapshot file into the local database, or reveal/delete existing snapshots.
