fix(growth,kernel,runtime,desktop): 50 轮功能链路审计 7 项断链修复

P0 修复:
- B-MEM-2: 跨会话记忆丢失 — 添加 IdentityRecall 查询意图检测，
  身份类查询绕过 FTS5/LIKE 文本搜索，直接按 scope 检索全部偏好+知识记忆；
  缓存 GrowthIntegration 到 Kernel 避免每次请求重建空 scorer
- B-HAND-1: Hands 未触发 — 创建 HandTool wrapper 实现 Tool trait，
  在 create_tool_registry() 中注册所有已启用 Hands 为 LLM 可调用工具

P1 修复:
- B-SCHED-4: 一次性定时未拦截 — 添加 RE_ONE_SHOT_TODAY 正则匹配
  "下午3点半提醒我..."类无日期前缀的同日触发模式
- B-CHAT-2: 工具调用循环 — ToolErrorMiddleware 添加连续失败计数器，
  3 次连续失败后自动 AbortLoop 防止无限重试
- B-CHAT-5: Stream 竞态 — cancelStream 后添加 500ms cancelCooldown，
  防止后端 active-stream 检查竞态
