* feat(wsl): open WSL host paths from Windows through one owner-routed capability (WSL-via-orcad C8)
* test(wsl): typed shell handler lookup for the WSL owner tests
* fix(wsl): read known WSL hosts through a registered accessor; e2e for the Windows folder picker
* fix(wsl): open the host-path entry filled in after a Windows pick; e2e screenshots
* test(wsl): read the e2e picker's default path through the main process env
* refactor(wsl): read a WSL host's distro from its record instead of a new accessor
* fix(wsl): skip the host browser only for a path Windows' picker or an Explorer drop filled in
A path left filled from an earlier pick on an SSH or paired host opens the host browser again, as it did before.
