/**
 * MCP Handler — autosnippet_rescan (增量知识更新)
 *
 * 保留已审核 Recipe，清理衍生缓存，全量/指定维度重新扫描，
 * 新知识通过批量提交走正常的进化架构。
 *
 * 流程:
 *   1. snapshotRecipes — 快照保留知识
 *   2. rescanClean — 清理衍生缓存
 *   3. Phase 1-4 全量分析
 *   4. RecipeRelevanceAuditor — 证据验证 + 快速衰退
 *   5. 构建 Mission Briefing（含 allRecipes + evolutionGuide）
 *   6. 返回给 Agent 按维度执行: evolve → gap-fill → dimension_complete
