📚 Description

Listhen uses an inline fork of open mainly to have bundler friendly xdg-open but later i end up with several improvements and inlining small libs to reduce size.

This PR, adds full type check, splits wsl and docker utils (i needed them for next steps) and remove many of the dead code from open as we simply need os open functionality.
