fix(cloud): Reconstruct launch state from GCE inventory

[fuyu0425]

Summary

• Reconstruct missing local cloud launch state from live GCE orchestrator metadata and role-labeled worker/evaluator inventory.
• Preserve runtime-added fleet identity across project, region, labels, owner, and IAP so takeover commands can list, SSH, collect, and teardown.
• Tune the remaining2 GCE worker placements to the current usable quota layout.

Testing

• uv run pytest tests/test_cloud_command.py::TestReconnect::test_resolve_cloud_context_reconstructs_state_from_live_orchestrator tests/test_cloud_command.py::TestReconnect::test_resolve_cloud_context_reconstructs_runtime_added_worker_fleets tests/test_cloud_command.py::TestReconnect::test_gce_live_role_discovery_scans_whole_configured_project tests/test_cloud_command.py::TestReconnect::test_gce_live_role_discovery_dedupes_by_project_zone_and_name tests/test_cloud_gce_provisioner.py::test_google_compute_client_lists_project_instances_from_aggregated_list tests/test_cloud_gce_provisioner.py::test_google_compute_client_lists_region_instances_from_aggregated_list
