fix(mcp): skip cmd /c wrapper for WSL target paths (#592)

* fix(mcp): skip cmd /c wrapper for WSL target paths

When the Claude config directory is set to a WSL network path
(e.g., \wsl$\Ubuntu\home\user\.claude), the MCP export should
not wrap npx/npm commands with cmd /c since WSL runs Linux.

- Add is_wsl_path() to detect \wsl$\ and \wsl.localhost\ paths
- Skip wrap_command_for_windows() when target is WSL path
- Add comprehensive tests for various WSL distributions

* chore(mcp): add debug log for WSL path detection

* refactor(mcp): optimize is_wsl_path with next() and rename variable
