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 Electron app now answers launcher-style sync argv (--sync-cli sync
[host|--snapshot|--merge] ... plus --help/--version) at entry, before any
window or display initialization, backed by a libsql binding of the shared
stats-sync engine. Works over SSH with no display server, so a remote
machine no longer needs the bun launcher. The launcher accepts --sync-cli
as a no-op so both invocation shapes stay equivalent.
Move snapshot/merge/quiescence engine and ssh helpers from launcher/sync
into src/core/services/stats-sync, parameterized on a minimal SyncDb
driver. The launcher binds it to bun:sqlite via launcher/sync/bun-driver;
the sync command becomes a thin adapter over the shared sync flow.
