fix: keyboard stability, host-only analytics, and auto-reply dedupe

- record analytics/usage only in the host app; the extension no longer opens the
  SQLite queues, so hiding the keyboard cannot hold WAL locks (0xdead10cc)
- sync clipboard history writes across processes so deletes made on one side
  are not reverted by the other
- guard memory-relief reentrancy on controller and telemetry sides to break
  the recursive crash loop
- resolve credentials off the main thread and migrate legacy keys once per
  install, so Keychain reads cannot be caught in the suspend window
- gate Volcengine ASR ping completion to once (SIGTRAP on double resume)
- treat same-text captures as the same logical copy and dedupe auto actions
  by content fingerprint within 30s, stopping Universal Clipboard storms
- realign version line to 2.1.0 (build 110)
