- Correct test cases to ensure proper relay IDs are switched.
- Add robust local IP resolution for relay-device bindings, including caching and inventory backfill.
- Introduce fast-path options for relay status and switch dispatch.
- Validate PHP extensions (`curl`, `sqlite3`) in edge agent images.
Transitioned from obsolete gateway object classes (`edge_gateway_shell_action_jobs_o`, `edge_gateway_shell_events_o`, `edge_gateway_shell_sessions_o`, `edge_gateway_update_jobs_o`) to the new agent implementation (`edge-gateway-agent/agent.php`).
This commit introduces unit tests, E2E tests, and implementation updates related to edge gateway lifecycle management, including update handling, artifact validation, and rollback mechanisms. It also refines routing, component interaction, and backend methods to improve update tracking, status transitions, and artifact management.
