v0.5.0 - Remember Smarter

[0.5.0] - 2026-03-04

Added

• C5 fix — Memory.remember/recall/forget use configured backend (SQLite, Qdrant, Chroma) instead of in-memory dict when backend != MEMORY.
• QdrantConfig — Memory(qdrant=QdrantConfig(url=..., api_key=..., collection=..., namespace=...)) for Qdrant Cloud or local.
• ChromaConfig — Memory(chroma=ChromaConfig(path=..., collection=...)) for Chroma vector backend.
• Namespace isolation — QdrantConfig.namespace scopes all operations; payload filter on search/list.
• WriteMode — WriteMode.SYNC (block until complete) vs WriteMode.ASYNC (fire-and-forget, default).
• Memory export/import — Memory.export() returns MemorySnapshot; Memory.import_from(snapshot) appends memories. JSON-serializable for GDPR export.
• Examples — examples/04_memory/qdrant_memory.py, chroma_memory.py, async_memory.py, export_import_memory.py.

Changed

• Agent and Memory handoff now use memory._backend_kwargs() for backend config.
• syrin[qdrant] and syrin[chroma] optional dependencies added to pyproject.toml.
