 - Added simple TenTap table serialization for rectangular tables, including entity decoding and escaped pipe characters, while continuing to block malformed table shapes.
 - Reworked the mobile properties panel into expandable Type/Status/Icon/Tags picker rows that show current values first and reveal chip choices on demand.
 - Added the first mobile Git sync plan model, covering local-only vaults, auth-required remotes, ready pull/push actions, active sync operations, and retryable failures.
