xSync 0.1.0

Initial xSync release for independent test vaults. Community listing remains a draft.

• Self-hosted end-to-end encrypted sync with explicit conflict review.
• Owner-local initialization, signed device enrollment, protected credentials and persistent device revocation.
• Host-sanitized UI, portable window timers, fixed self-exclusions, and per-device sync rules.

Validation: 93 default tests, type checking, both plugin builds, package checks and a dependency audit passed locally. CI also verifies PostgreSQL contracts, race detection, multi-device recovery and native IndexedDB crash recovery.

Target platforms: macOS and iOS; minimum host 1.14.5. Android secure storage is not implemented. Fresh Mac/iPhone onboarding/credential changes, coordinated backup restoration and production security validation remain incomplete. iOS depends on an internal native host bridge; background execution is not guaranteed.

See README and docs/SETUP.md before use. Keep the sync key on your own devices and offline backup; do not upload it to the server.
