Bug Fixes:

• Core: add() (Memory and AsyncMemory) no longer reports records the vector store rejected as successful ADD events. Only records that were actually inserted are written to history, entity-linked, and returned. If none of the extracted memories could be inserted, add() now raises VectorStoreError instead of returning memories that were never stored (#7066)
• Core: Restore the context-manager protocol on Memory (with Memory() as m:) and AsyncMemory (async with AsyncMemory() as m:), which closes the instance on exit (#7354)
• LLMs: The AWS Bedrock Anthropic path now returns the first Converse content block that carries text instead of always reading content[0]. Claude reasoning models can emit a reasoningContent block before the text block, which previously made the call fail with a KeyError (#6369)
• Vector Stores: Turbopuffer filters now apply every operator (eq, ne, gt, gte, lt, lte, in, nin). Only gte and lte were read before, so any other operator was silently dropped and the query returned unfiltered results. An unsupported operator now raises ValueError (#6564)
• Vector Stores: Turbopuffer search() scores now respect distance_metric. With euclidean_squared, the unbounded squared distance maps to 1 / (1 + distance) instead of 1 - distance, which went negative and inverted ranking for any distance above 1 (#6559)
• Vector Stores: S3 Vectors search() scores are now metric-aware. With euclidean, the distance maps to 1 / (1 + distance) instead of max(0, 1 - distance), which collapsed most scores to 0 (#6547)
