Subject: [PATCH] chore(ai): event schema validation tool + fixes

- Created `scripts/agent/validate-events.mjs` to validate all event builders.
- Fixed `buildViewEvent` to generate a fallback `d` tag for kind 30079 compliance.
- Relaxed `REPOST` schema validation to allow empty content (blind reposts), per NIP-18.
- Updated `docs/nostr-event-schemas.md` to reflect schema changes.
