[Windows] LSP plugins fail with spawn ENOENT — missing shell:true for .cmd files

Bug Description

The typescript-lsp@claude-plugins-official plugin (and all npm-installed LSP plugins) fail on Windows with:

spawn typescript-language-server ENOENT

This error appears in /doctor output and recurs every session.

Root Cause

The LSP server manager in cli.js spawns language servers using Node.js child_process.spawn() without shell: true in the spawn options.

On Windows, npm global installs create .cmd wrapper scripts (e.g., typescript-language-server.cmd), not native executables. Without shell: true, Node.js spawn() cannot resolve .cmd files — it only looks for .exe, .com, etc.

Buggy Code Location

cli.js (bundled/minified), function Jb4() at approximately position 7325624:

spawn(command, args, {
  stdio: ["pipe", "pipe", "pipe"],
  env: ...,
  cwd: ...,
  windowsHide: true
  // MISSING: shell: true
})

Suggested Fix

Add shell: true conditionally for Windows:

spawn(command, args, {
  stdio: ["pipe", "pipe", "pipe"],
  shell: process.platform === "win32",  // ADD THIS
  env: ...,
  cwd: ...,
  windowsHide: true
})

Scope of Impact

This affects all LSP plugins that use npm-installed language servers on Windows:

• typescript-lsp (typescript-language-server)
• php-lsp (intelephense)
• Any other plugin where the binary is an npm global .cmd wrapper

LSP plugins using native executables (clangd, rust-analyzer, gopls) are not affected since they ship real .exe files.

Verification

• typescript-language-server IS correctly installed and accessible via shell:

``
C:\Users\dhdav\AppData\Roaming\npm\typescript-language-server.cmd
``

• Running typescript-language-server --stdio from a terminal works fine
• The issue is exclusively that spawn() without shell: true cannot find .cmd files on Windows

Current Workaround

Disable the plugin in ~/.claude/settings.json:

{
  "plugins": {
    "typescript-lsp@claude-plugins-official": false
  }
}

Environment

• OS: Windows 10 Home 10.0.19045
• Node.js: v22.x
• Claude Code: latest (npm global install)
• typescript-language-server: installed globally via npm
