feat(server): 实现 LSP 管理 REST API

- 新增 /api/lsp/servers 端点，列出所有语言服务器
- 新增 /api/lsp/servers/:id 端点，获取服务器详情
- 新增 /api/lsp/servers/:id/install 端点，安装服务器
- 新增 /api/lsp/servers/:id/start 端点，启动服务器
- 新增 /api/lsp/servers/:id/stop 端点，停止服务器
- 新增 /api/lsp/diagnostics 端点，获取诊断信息
- 新增 /api/lsp/running 端点，获取运行中服务器列表
- core/lsp 添加 stopServer, getRunningServers, isServerRunning 方法
