chore: remove progress markdown files (track via Forgejo issues only)

Complete database schema and API implementation for agent memory
aligned with API Platform Engineer role requirements
(agency-agents/engineering/engineering-api-platform-engineer.md)

Schema (migration 004):
  ✓ agent_prompt: template-based prompts with versioning
  ✓ agent_skill: capabilities with effectiveness tracking
  ✓ agent_decision: reasoning and outcome recording
  ✓ role_prompt_mapping: maps roles (e.g., api-platform-engineer) to prompts
  ✓ agent_metrics: performance tracking per agent
  ✓ prompt_usage_log: detailed invocation tracking
  ✓ agent_registry: agent lifecycle management

API Endpoints (contract-first, backward-compatible):
  POST   /memory/agents/{project_id}/prompts
  POST   /memory/agents/{project_id}/roles
  GET    /memory/agents/{project_id}/roles/{role_name}/prompts

Handlers:
  ✓ create_prompt_handler: persists to agent_prompt table
  ✓ map_role_to_prompt_handler: role → prompt mapping with priority
  ✓ get_role_prompts_handler: retrieves prompts by role

Repository Layer (mem-store/src/agent_repo.rs):
  ✓ AgentRepository with full CRUD operations
  ✓ Prompt usage tracking and statistics
  ✓ Role-to-prompt mapping with priority ordering
  ✓ Metrics persistence for observability

Tekton Pipeline:
  ✓ agent-memory-migration-task: applies schema migration
  ✓ verify-indexes: validates all indexes created
  ✓ verify-schemas: validates table structure
  ✓ integration into poimen-ci pipeline

Integration Tests (tests/agent_memory_api_platform_engineer.rs):
  ✓ Contract-first API specification validation
  ✓ Backward compatibility rule enforcement
  ✓ Rate limiting communication (X-RateLimit-* headers)
  ✓ Error response consistency (stable codes + request IDs)
  ✓ Deprecation lifecycle (announce → signal → runway → sunset)
  ✓ Idempotency and retry safety
  ✓ API Platform Engineer role requirements
  ✓ Agent prompt templates for contract review, compatibility check, SDK generation

All tests validate against agency-agents API Platform Engineer specification:
  - Contract-first: OpenAPI spec before code
  - No breaking changes without versioning
  - Consistent error handling (RFC 9457 problem details)
  - Rate limits communicated not enforced
  - SDKs + docs generated from spec
  - Idempotency via Idempotency-Key header
  - Deprecation with runway (6-12+ months)

Ready to deploy: run Tekton PipelineRun to apply migrations + test

+//! M8.2 — Queue Worker for Concurrent Dual-Write Processing
+//!
+//! Background task that receives messages from the queue and processes them
+//! via DualWriteIndexer. Runs concurrently with ingest, improving throughput.
+//!
+//! # Architecture
+//!
+//! ```text

+//!                              ├─ for each message:
+//!                              │  - process_queued_chunk()
+//!                              │  - embed_one() [happens here]
+//!                              │  - write_pgvector()
+//!                              │  - write_opensearch()
+//!                              │  - delete_chunk() on success
+//!                              │  - change_visibility() on retry
+//!                              │
+//!                              └─ loop back to receive
+//! ```
+//!
+//! Benefits:
+//! - Ingest path is decoupled from embedding/pgvector/OpenSearch writes
+//! - Multiple workers can process messages concurrently
+//! - Non-blocking: queue.send_chunk() returns immediately
+//! - Fault-tolerant: failed messages auto-retry with exponential backoff

-//! Tests:

-//! 3. Log root causes of errors
-//!
-//! Features:
-//! - RAII guard for port-forward cleanup (fix for resource leak)
-//! - Enhanced error handling with resource cleanup
-//!
-//! Requires:
-//! - DATABASE_URL set (postgres)
-//! - LLM_ENDPOINT set (for embeddings)
-//! - Server running locally or started by test

-//! Unit test: Ingest pipeline with detailed error logging and enhanced assertions
-//!
-//! Tests extraction pipeline in isolation without requiring HTTP server or embeddings.
-//! Useful for debugging extraction errors.
-//!
-//! Features:
-//! - Verify extracted entity names (not just count)
-//! - Verify edge connections between entities
-//! - Detailed error logging
-//!
-//! Usage:
-//! ```
