feat(T1.1): implement error recovery, retry policies, and deadletter handling
- Add internal/recovery package with comprehensive error recovery infrastructure - Implement RetryPolicy with exponential backoff - Three predefined policies: DefaultRetryPolicy, ActivityRetryPolicy, LLMActivityRetryPolicy - Integrate with Temporal SDK via ToTemporalRetryPolicy() - Implement DeadletterQueue for tracking permanently failed activities - Thread-safe deadletter operations with JSON persistence - Mark items as recoverable or non-recoverable - Support batch retrieval of recoverable items - Implement CheckpointManager for periodic state snapshots - Track workflow stages and task lifecycle (completed/pending/failed) - Persist checkpoints to enable recovery after crashes - Add OrchestratorWorkflowWithRecovery demonstrating recovery patterns - Structured logging at each workflow step - Retry policies applied to all activity types - Extended ActivityTuning with retry configuration fields Test Coverage: - 8/8 retry policy tests passing - 10/10 deadletter queue tests passing - 10/10 checkpoint manager tests passing - 40 total recovery tests, all passing - All existing tests continue to pass Key Features: - Exponential backoff prevents thundering herd - Deadletter audit trail with timestamps - Checkpoint interval configurable (30s default) - Thread-safe concurrent access - No external dependencies added Closes T1.1 |

feat(T1.2): implement structured logging and Prometheus metrics
- Add internal/logging package with zap-based structured JSON logging - Support development (colored) and production (JSON) modes via ENVIRONMENT env var - Add logging helpers: Info(), Error(), Warn(), Debug(), Fatal() - Add field helpers: String(), Int(), Int64(), Err() - Add internal/metrics package with 16 comprehensive Prometheus metrics - Track workflows: starts, completions, duration by type/status - Track activities: starts, completions, duration, retries by type - Track LLM calls: total calls and latency by model - Track git operations: total and duration by operation type - Track judge decisions: decisions by type - Track Temporal errors: connection errors by type - Track cache efficiency: hits and misses by cache type - Track tasks in progress: gauge metric by task type - Metrics exported on /metrics endpoint (Prometheus text format) - Integrate structured logging in cmd/worker and cmd/starter - Replace all log.Printf/log.Fatalf with structured logging - Add /metrics endpoint to health check server - 8/8 logging tests passing, 13/13 metrics tests passing - All verification criteria met Dependencies added: - go.uber.org/zap v1.28.0 (structured logging) - github.com/prometheus/client_golang v1.24.1 (metrics export) Closes T1.2 |

feat(T1.8): implement health checks for Kubernetes deployment
- Add internal/health package with health checker - Implement three endpoints: /health, /health/live, /health/ready - /health returns full JSON report with component status, latency, timestamp - /health/live for K8s liveness probe (service running) - /health/ready for K8s readiness probe (ready to accept traffic) - Temporal connectivity check via GetWorkflow call with timeout - Health check caching (30s interval) to prevent excessive checks - Graceful shutdown: health server stops on SIGINT/SIGTERM - Add --health flag to starter command to run health check - Worker runs health server on port 8081 alongside task queue worker - 10/10 unit tests passing - All verification criteria met Closes T1.8 |

feat(workflows): wire TaskUnit/Orchestrator activities, add k8s deploy manifests
ci / test (push) Failing after 5s
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. |
