refactor(sync): collapse 11 sync args into forwarded token array

- Replace syncHost/syncSnapshotPath/… with syncCliTokens: string[] passed verbatim to --sync-cli sync
- Move sync CLI validation from launcher to parseSyncCliTokens (app-side single owner)
- Extract resolveImmersionDbPath to shared db-path.ts importable by both launcher and app
- Delete driver.ts; inline types into libsql-driver.ts and hard-wire openLibsqlSyncDb
- Drop OpenSyncDb injection from mergeSnapshotIntoDb and createDbSnapshot
