feat: add heartbeat monitor and vector memory search (Tier 2)
...
Heartbeat:
- HeartbeatMonitor with 5 checks: gateway, model, channels, memory, disk
- Configurable interval, failure threshold, notification channel
- Recovery notifications when health restores
- 25 new tests
Vector Memory Search:
- EmbeddingProvider interface with OpenAI, Gemini, Ollama, LlamaCpp backends
- SQLite-backed VectorStore with cosine similarity search
- Text chunker with paragraph-aware splitting and overlap
- HybridSearch merging keyword + vector results with configurable weight
- Background indexer with dirty-namespace tracking
- Graceful fallback to keyword search when embeddings unavailable
- 51 new tests
Config: automation.heartbeat + memory.embedding schema sections
Total: 950 tests passing, all types clean

feat: add persistent memory system (Phase 2)
...
Implement file-based persistent memory with read/write/search tools:
- MemoryStore with namespace-scoped JSON storage
- memory-read, memory-write, memory-search builtin tools
- Auto-extraction of facts during context compaction
- Configurable via memory.enabled, memory.dir, memory.max_context_tokens
