Consolidates 3 separate memory databases (semantic_memory.db, swarm.db
memory_entries, brain.db) into a single data/memory.db with facts,
chunks, and episodes tables.
Key changes:
- Add unified schema (timmy/memory/unified.py) with 3 core tables
- Redirect vector_store.py and semantic_memory.py to memory.db
- Add thought distillation: every Nth thought extracts lasting facts
- Enrich agent context with known facts in system prompt
- Add memory_forget tool for removing outdated memories
- Unify embeddings: vector_store delegates to semantic_memory.embed_text
- Bridge spark events to unified event log
- Add pruning for thoughts and events with configurable retention
- Add data migration script (timmy/memory_migrate.py)
- Deprecate brain.memory in favor of unified system
