The linux relaunch gate compares the running desktop's exe path
(relaunch target, read from /proc/<pid>/exe — kernel-canonicalised)
against the checkout's unpacked-app prefix with a raw case-pattern.
On hosts where /home is a symlink to /var/home (e.g. Fedora), the two
sides spell the same tree differently (/home/... vs /var/home/...) and
the gate false-positives "skew", telling the user to reinstall the
desktop app after every successful self-update.
Canonicalise both sides with readlink -m (which resolves existing
leading components without requiring the full path to exist, unlike
-f) before the prefix compare. No-op when both sides already agree.
