- Add comprehensive Temporal usage guide referencing homelab REST API gateway
- Update integration tests to skip when Temporal is not accessible (CI environments)
- Tests now gracefully skip instead of failing when TEMPORAL_HOSTPORT is unreachable
- Enables CI to pass without requiring Temporal access (no new resources needed)
- Unit tests continue to pass, integration tests skip with clear messaging
Implements real activity-calling logic in OrchestratorWorkflow and
TaskUnitWorkflow (previously stubs), adds GitDiffActivity, and expands
PlanningActivity's I/O to carry repo path and prior task results.
Adds k8s/ deployment manifests (worker Deployment, orchestrator Job,
Kustomize base) for the poimen-workflows Temporal worker, using a
dedicated Kubernetes namespace `poimen` and Temporal namespace
`poimen-harness` rather than sharing the Temporal server's own
`temporal`/`production` namespaces.
