* fix(wsl): run wsl.exe probes from the system root, never the profile
WSL holds wsl.exe's working directory busy for about its idle timeout
after the probe exits. Since #29209 the orcad startup probe ran in the
profile, so a temporary orca serve profile could not be deleted for about
a minute (diagnosed in #29845).
* test(orcad): drop the WSL profile-hold wait from serve parity
Reverts #29845's extended EBUSY retry: wsl.exe no longer runs in the
profile, so nothing outside the test's process tree holds it.
* build(cli): list the WSL spawn-directory module in the CLI typecheck project
