VoipAppz Builder 0.1.8

Run the app in WSL2 on Windows, v0.1.8

On Windows, an app folder under \\wsl.localhost\<distro> (or \\wsl$,
\\?\UNC\wsl.localhost) now means the app runs inside that distro: git,
`make setup`, `make dev` and the coding agent run through
`wsl.exe -d <distro> --cd <linux path>` with the distro's login shell, so
its own tools and Claude sign-in are used. Onboarding accepts such a
folder; other network shares are still refused.

Pre-flight in WSL mode checks wsl.exe, that the distro runs WSL2 (the
previews reach the dev server on localhost, which only WSL2 forwards),
git/make/bash/curl inside the distro, and free space on both the distro
and the Windows drive that holds its disk.

The write boundary checks the agent's Linux paths by their
\\wsl.localhost names, so symlinks and `..` are resolved as on a local
disk. Commands in the distro get only PATH and the variables Builder adds.
