Port the normalized, priority-ordered (static > dynamic > search) profile
deduplication into the Python SDKs, injecting one owned memory block per
request that replaces the prior block rather than accumulating. Dedup is
request-local (no shared state), so it stays correct under concurrency.
Covers OpenAI, Agent Framework (middleware + context provider), Cartesia,
and Pipecat.
