- Add Sandbox API OpenAPI spec with filesystem and process endpoints
- Filter REST API spec to only include user-facing endpoints (ApiKeyAuth)
- Remove admin/internal endpoints (Supabase-only, AccessToken-only)
- Add sync script to fetch and transform specs from infra repo
- Add GitHub Actions workflow for scheduled sync every 6 hours
- Fix OpenAPI 3.0 compatibility issues in generated specs
