Bump to 0.9.0

Adds a shadcn Alert for the "no devices connected" hints on Control
and Replay, then reworks the navigation: an animated hamburger/close
toggle, a redesigned mobile drawer (brand header, icon nav rows,
theme/logout moved into the drawer footer), and a desktop tab strip
restyled to match the drawer's active-tab treatment.
