LSP: ENOENT on Windows — spawn cannot find .cmd shim executables

Description

LSP tool fails on Windows with ENOENT: no such file or directory, uv_spawn 'typescript-language-server'.

Environment

• Windows 11 Pro
• Claude Code latest (CLI)
• typescript-lsp@claude-plugins-official plugin enabled
• typescript-language-server@5.1.3 installed globally via npm
• Binary confirmed in PATH: C:\Users\...\AppData\Roaming\npm\typescript-language-server.cmd

Steps to Reproduce

1. Install typescript-language-server globally on Windows (npm i -g typescript-language-server typescript)
2. Enable the typescript-lsp plugin
3. Use the LSP tool on any .ts file (e.g., hover, documentSymbol, goToDefinition)

Error

Error performing documentSymbol: ENOENT: no such file or directory, uv_spawn 'typescript-language-server'

Root Cause

On Windows, npm installs global packages as .cmd batch script shims (e.g., typescript-language-server.cmd), not as directly executable binaries.
