config(claude): 角色路由 hook (dev/test/pm) + role-router 单测

- claude-config/hooks/role-router.mjs
  按 user prompt 关键词检测当前角色，注入推荐 agent hint
  - dev: 开发/实现/重构/修(复|bug)/dev/implement/refactor/fix/feature → executor/debugger
  - test: 测试/单测/回归/QA/test/regression/spec → qa-tester/test-engineer/verifier
  - pm: 产品/需求/排期/规划/PM/product/PRD/roadmap → planner/analyst/scientist
  支持多角色同时命中
- claude-config/hooks/role-router.test.mjs
  10 fixture 单测 (含 subprocess pipe integration), 10/10 PASS
- claude-config/settings.json.snapshot.20260426
  全局 settings.json 快照, hooks.UserPromptSubmit 接 keyword-detector + role-router
- claude-config/README.md
  设计/安装/测试 文档
