feat(pi-web-search): 统一 web_search/web_fetch 并由主模型路由搜索厂商

7 个按厂商命名的搜索工具收敛为 2 个统一工具,schema 与提示词不再暴露
provider 概念:web_search 由当前主模型按内置规则在 Tavily/Exa/Keenable
间路由(会话内 LRU 缓存,失败按可用性降级),web_fetch 固定走 Exa 并
静默降级。三家均改为纯 fetch 直连——Exa 直接对 mcp.exa.ai 发 JSON-RPC
并缓存会话,彻底移除 pi-mcp-adapter、@tavily/pi-extension 与
@keenable/pi-search 依赖。
