WSL path conversion produces invalid /mnt/wsl.localhost/ path instead of native WSL path

[MayoLars]

When using "Claude Code (WSL)" with a solution opened from a WSL path, the extension
produces an invalid cd command:

bash: cd: /mnt/wsl.localhost/Ubuntu/home/mayolars/App: No such file or directory

The extension is converting the Windows UNC path \\wsl.localhost\Ubuntu\home\mayolars\App
to /mnt/wsl.localhost/Ubuntu/home/mayolars/App, which doesn't exist inside WSL.

Expected: The path should be converted to the native WSL path /home/mayolars/App
(strip \\wsl.localhost\Ubuntu and keep the rest).

Environment:

• Windows 11, WSL2 (Ubuntu)
• Visual Studio 2026
• Extension mode: Claude Code (WSL)
• Solution located at \\wsl.localhost\Ubuntu\home\mayolars\App

Suggested fix:
The conversion should detect the \\wsl.localhost\<distro>\ prefix and strip it,
since that prefix is how Windows addresses WSL paths — inside WSL, the root is /.

For example, in the path conversion logic:

• Input: \\wsl.localhost\Ubuntu\home\mayolars\App
• Strip: \\wsl.localhost\Ubuntu
• Result: /home/mayolars\App

Paths under \\wsl$\ should be handled the same way (older UNC format).

Paths starting with a Windows drive letter (e.g. C:\Projects\...) should still
convert to /mnt/c/Projects/... as they do now — that conversion is correct for
accessing Windows drives from within WSL.
