The old ErrRelaunchAttempt name was ambiguous — it reads as though the
relaunch attempt failed, when it actually signals success. Rename to
ErrRelaunchSucceeded and update comments at every call site to clarify
that this is not a real error but a sentinel indicating the elevated
child process completed the operation successfully.
Also fix a bug in WSL's launchElevate where a failed elevated process
was incorrectly wrapped with the sentinel, causing callers to treat the
failure as success and print "Machine init complete."
