site: review — SmartMover (graduates from find)

New review under category `automation` (introduced for Apple
Shortcuts and similar workflow graduates — none of the existing
review categories fit). Hero registered in src/lib/hero.ts so the
grid card renders. Find marked `promotedTo: smartmover-shortcut`.

Also: HERO_SLUG bumped from superkey → monitorcontrol on the home
page (today's pick).
