fix: 缓存系统全面加固 — 版本失效 + 死代码清理 + 防御性改进

Browse Source 
基于缓存审查报告 + Claude Code 交叉审查的反馈：

P0+ 语义缓存版本失效:
- sync.py: 文档变更后清空语义缓存，防止返回过时的 images/sources
- document_routes.py: 删除文档时同步清理缓存
- kb_routes.py: 删除向量库时同步清理缓存

P1.5 cache_type 包含式校验:
- intent_analyzer.py: != "rag_answer" 改为 == "intent_analysis"

P2+ Rerank Cache 版本失效:
- cache.py: increment_kb_version 时同时清空 rerank_cache

P1+P6 死代码清理:
- agentic.py: 移除未使用的 SemanticCache 实例和相关导入
- agentic_base.py: 移除未使用的语义缓存配置导入
- cache.py: 移除 _compute_doc_hash 和未使用的 doc_ids 参数
- engine.py: 移除 set_query_result 调用中的 doc_ids 参数

P7 缓存质量门槛:
- config.py: CACHE_MIN_SCORE 从 0.0 改为 0.3
