* feat(memory): add opt-in relevance-aware retrieval ranking Add a deterministic, network-free lexical relevance strategy for DeerMem (issue #4495): memory_search ranks every fact in scope by idf-weighted token overlap combined with confidence, with optional greedy-MMR diversity against near-duplicate facts; prompt injection ranks facts against the current-turn query threaded from DynamicContextMiddleware through the new optional `query` keyword on MemoryManager.get_context/aget_context. Defaults preserve the legacy confidence-only behavior exactly; no prompt, storage-format, or vector/embedding-dependency changes.

Cache MMR token sets and stop selection at result or injection budgets. Document retrieval-adapter precedence and add regression coverage. Refs #4495.
