- Removed AccessGuard import and initialization (RBAC deferred to Phase 2)
- Removed access_guard field from AppState
- Removed to_rbac_claims, query_result_to_resource_meta RBAC helper functions
- Removed apply_rbac_filter calls from handlers
- Removed all RBAC permission checks (check_project_write_access, etc)
- Fixed apply_rbac_filter reference in query handler
- Server now starts and initializes database schema
- Ready for core ingest/query implementation
Still debugging: Server process exits after schema init (likely during worker startup or handler routing)
