feat: wire rule registry and client-authenticated callback into server runtime

- Add ruleRegistry and onClientAuthenticated options to YonexusServerRuntime
- Dispatch rewritten rule messages (rule::sender::content) to rule registry
- Guard onClientAuthenticated behind promoteToAuthenticated return value
- Fix transport message handler: use tempConn directly when ws is in temp state,
  preventing stale _connections entry from causing promoteToAuthenticated to fail
- Close competing temp connections with same identifier on promotion
- Expose __yonexusServer on globalThis for cross-plugin communication
- Remove auto-failure on admin notification miss; pairing stays pending
