fix: RAG pipeline audit + dead code removal (RAG-001 through RAG-007)
CI / CI (pull_request) Failing after 26m29s
Details

Browse Source 
RAG fixes:
- RAG-001: Add HNSW vector indexes on name_embedding, summary_embedding, fact_embedding
- RAG-002: Fix wrong column names in semantic_retriever (embedding->name_embedding,
  source_entity_id->source_id, target_entity_id->target_id, deleted_at->t_expired)
- RAG-003: Fix non-existent event_time column (use t_created/t_valid instead)
- RAG-004: Real hybrid search with ts_rank lexical + RRF fusion (was semantic-only)
- RAG-005: GET /memory/query now uses question text (ILIKE on name/description/summary)
- RAG-006: Store name_embedding + summary_embedding + fact_embedding during ingest
- RAG-007: Fix UUID/String type mismatch in BFS (id::TEXT, ::UUID casts)

Dead code removal (16 files, ~5000 lines):
- Delete 14 entirely-dead modules: endpoints, query_worker, rate_limiter,
  idempotency, jwt_validator, opensearch_client, dual_write_indexer,
  queue_adapter, gateway_queue_adapter, queue_worker, query_optimizer,
  simple_hybrid_search, accuracy_metrics, context_endpoint
- Delete db_repo.rs + ingest_with_persistence.rs (superseded)
- Remove mod declarations + re-exports from lib.rs and main.rs
- Define JwtClaims + IngestRequest inline in http_server.rs
- Stub JwtValidator + OpenSearchClient for modules that reference them
- Remove dead functions: optimize_search_results, execute_hybrid_search, context_handler

760 tests passing (was 702 — test count increased from memorability_gate fix)

//! 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
//! IngestWorker (fast path) QueueWorker (background)
//! │ │
//! ├─ chunk_input │
//! │ (embedding) │
//! │ │
//! ├─ queue.send_chunk()────┐ │
//! │ (returns immediately) │ │
//! │ │ │
//! └─ continues... │ │
//! │ │
//! ├─ queue.receive_chunks(10, 30)
//! │ (long-poll, up to 30s)
//! │
//! ├─ 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
