Subject: [PATCH] fix(mcp,cli): read retrieval strategy from settings + update
 CLI memory types (plan 21 F8)

- memoryTools.ts: replace hardcoded retrievalStrategy:"exact" with getMemorySettings()+toMemoryRetrievalConfig(); fallback to "exact" on catch
- memory.mjs: VALID_TYPES updated to ["factual","episodic","procedural","semantic"]; default changed from "user" to "factual"; legacy types (user/feedback/project/reference) emit deprecation warning and map to "factual"
- tests: mcp-memory-tools-strategy.test.ts (7 cases) + cli-memory-types.test.mjs (12 cases)
