fix(review): ce-code-review P1+P2 修复 — 安全/可靠性/性能
...
P1 安全与可靠性（4 项）：
- wecom: verify_signature 增加时间戳新鲜度校验（5 分钟窗口防重放）
- cache: should_cache 在 per_user_namespace 开启时拒绝 user_id=None
匿名请求，避免跨用户缓存泄漏（安全要求 a/e）
- channels: webhook receive_message 异常兜底，防止 500 触发平台重试风暴
- app: shutdown 调用 close_all_adapters + await _pending_webhook_tasks，
防止 httpx 连接泄漏和丢失 IM 回复
P2 效率与可维护性（5 项）：
- feishu: _TOKEN_CACHE_TTL 300 → 6900（2h 减 5min 余量，避免 24x 过频刷新）
- channels: _pending_webhook_tasks 有界化（2x 并发上限时 429 拒绝）
- gateway: quota 检查每 period 单次 get_usage，复用 summary 检查 token+cost
- cache_key: generate_cache_key 合并为单次 SHA-256（消除 8-10 次冗余哈希）
- config: ProviderConfig.get_api_key 移除未用的 secrets_store 参数
P3 去重（1 项）：
- channels: _process_inbound_message DIRECT_CHAT 路径提取 _direct_chat 辅助函数
测试：
- test_wecom: 时间戳改用 int(time.time())，新增 test_expired_timestamp_rejected
- test_cache: should_cache 测试覆盖匿名拒绝 + namespace_off 兼容
- test_config_migration: get_api_key 测试适配新签名
- channels/config_migration/quota_enforcement 测试全部通过

feat: P0 production hardening — LLM cache, semantic routing, state persistence
...
U1: LLM Cache Core (exact + semantic match, InMemory + Redis backends)
U2: Cache integration into LLMGateway with CacheConfig
U3: Semantic Router as Layer 1.5 in CostAwareRouter
U4: UsageStore persistence (Redis Hash + InMemory fallback)
U5: CascadeStateStore persistence (Redis INCR + InMemory TTL)
U6: EvolutionStore interface unification (Protocol + PostgreSQL backend)
U7: Configuration integration + E2E tests
Code review fixes:
- P0: date iteration bug (day>=28), semantic router index never built,
Redis connection leak (per-call → persistent pool)
- P1: cache degradation recovery, semantic_search degradation,
double miss counting, asyncio.Lock for PG init, LIMIT on queries,
__import__ anti-pattern → _utcnow()
- P2: InMemory TTL cleanup, embedding preservation on put(),
data TTL = max(exact_ttl, semantic_ttl)

feat: optimize chat response speed for sub-1s first token latency
...
- Add HeuristicClassifier to replace LLM quick_classify with zero-cost
local heuristic (keyword/length/code-pattern scoring), gated by
router.classifier config (default: heuristic)
- Add parallel tool execution in ReActEngine via asyncio.gather for
multiple independent tool_calls, gated by parallel_tools param
- Add AsyncWriteQueue for non-blocking session persistence with WAL
buffer, gated by async_writes param on SessionManager
- Add httpx.Limits connection pool config to all LLM providers
- Add router config section to ServerConfig and agentkit.yaml
- All optimizations have config switches for safe rollback
