Security update
- All messages are encrypted end-to-end — chats protected in transit and at rest
- HMAC-SHA256 unlock keys; vault password verified server-side only
- Sessions and unlock keys stored in macOS Keychain
- Per-account chat isolation — sign in or out resets local state cleanly
- API rate limits, tier gating, and restricted CORS on the edge
- Privacy mode skips cloud API and sync entirely
