feat(host-internal): 多语言 LSP 接入与 get_diagnostics 动态工具描述#71
Conversation
扩展 provider 目录与按文件后缀路由，并将 PATH 解析抽象为通用 resolveCommandOnPath；运行时仍仅探测 TypeScript 语言服务器。
新增 LspProviderSession 与 LspOrchestrator，LspService 改为门面；TypeScript 端到端行为保持不变。
注册 pyright、gopls PATH 解析与 install 模块（npm/go），Desktop 安装命令改用统一 installLspProvider。
注册 rust-analyzer、clangd PATH 解析，扩展 languageId 映射；clangd 安装仍走平台包管理器指引。
jdtls 使用 Java 21+ 自定义启动器与工作区 data 目录；OmniSharp 支持 PATH 与 dotnet+dll 回退。
扩展 LSP 支持后缀与工具描述，get_diagnostics 与写后 append 按后缀自动路由到已安装语言服务器。
更新 agent-core/host 边界说明；Desktop LSP 快照支持 installKind，仅对 npm/go/rustup 显示一键安装。
合并工具定义时传入 probe 后就绪的 provider 列表，避免模型误以为未安装语言也可用

Write append masks missing server
Medium Severity
After a successful write, post-edit LSP append now runs for every in-scope extension, not only TypeScript/JavaScript. When the matching language server was never probed as ready, getDiagnosticsForPath fails, and the broad catch still appends “diagnostics pending or timed out,” which misleads the model about a missing server versus a slow analysis.

hasReadyProviderForPath 过滤未 probe 就绪的后缀；catch 仅对 LspTimeoutError 追加 pending 文案，避免无 server 被误判为慢分析。

Summary
LspOrchestrator+LspProviderSession），按文件后缀路由至 typescript-language-server、Pyright、gopls、rust-analyzer、clangd、jdtls、OmniSharp。get_diagnostics工具描述按当前 probe 就绪的 provider 动态生成，避免模型误以为未安装语言可用；不写 HTML/CSS 负向提示。Test plan
