The updater keeps a Tauri/Cocoa event loop alive while it relaunches the
desktop, and that loop can outlive app.exit(0). Relying on Drop alone
left a *successful* update looking active -- a live pid holding a fresh
marker -- which blocked desktop startup and, now that the marker is also
the cross-process update lock, every subsequent updater until the age
ceiling expired.
Release explicitly once all install-tree mutations are done, before the
relaunch. complete() is idempotent so Drop still covers the failure and
panic paths. Arms a process-exit fallback so a wedged event loop cannot
leave a finished updater lingering as a live pid.
