The version number shown in the PI only updates via the 'projects' push,
which only fires from onPropertyInspectorDidAppear (i.e. when a
different button is clicked, forcing the PI to re-appear). After
'Check for Updates' completes and the plugin process restarts, an
already-open PI kept showing the pre-update version indefinitely.
Two changes: send a final 'Updated to vX — restarting…' status right
before process.exit(0) so the update message doesn't hang on
'Updating…', and push sendProjectsToPI() once on every plugin startup
(after streamDeck.connect()) so a PI that survived the restart gets
the new version immediately instead of waiting for an unrelated button
click.
