v0.3.0 — Production Quality

What's New

Quality (10 iterations)

• 107 quality tests on real-world agent memory data (10 categories, all passing)
• Benchmark suite — <1ms queries, 10K+ inserts/sec
• LSH pre-filtering for O(n log n) consolidation
• Versioned migration system (PRAGMA user_version)
• 16 TypedDict return types + py.typed marker
• Custom exception hierarchy — AgentMemError, MemoryNotFoundError, InvalidTierError, EmbeddingError
• WAL checkpoint management + transaction safety (context manager)

Bug Fixes

• Namespace isolation — content_hash UNIQUE now scoped to (hash, namespace)
• update_memory dedup — archives old memory even on hash collision
• HTTP security — default bind 127.0.0.1, configurable --host/--cors-origin
• Empty content validation in remember()
• LIKE wildcard escape in namespace queries
• HTTP param validation — 400 on invalid params, not 500
