nessi 16fc6cb1b6 feat: add gateway bootstrap endpoint with token-based authentication
Add Bootstrap and AgentSyncBundle handlers to gateway package with X-Gateway-Bootstrap-Token header authentication. Implement UpsertByName repository method for idempotent gateway registration. Update gateway entrypoint script to auto-generate keys and bootstrap gateway on first run, persisting gateway ID to disk. Add GATEWAY_BOOTSTRAP_TOKEN config and update environment variables for gateway name, bootstrap URL, and sync URL.
