Claude-Session-ID für SDK-Fortsetzung

- events.ts: Session-ID aus claude-result speichern via set_claude_session_id
- claude.rs: load_claude_session_id() lädt ID der aktiven Session
- claude.rs: send_to_bridge_full() mit resumeSessionId Parameter
- claude-bridge.js: sendMessage() akzeptiert resumeSessionId
- Bridge nutzt sessionId in query() Optionen für SDK-Fortsetzung

Ermöglicht nahtlose Konversations-Fortsetzung auf SDK-Ebene.
