Unify compact workspace controls and panel transitions, move directory actions into the context menu, and remove backlink UI.
Reorganize settings with searchable sections, per-setting resets, shortcut search, and accurate save feedback.
Remove sharing UI, APIs, authentication helpers, and storage code; provide a transactional cleanup script with retirement tests. Reject directories during orphan image cleanup and cover mixed-batch preservation.
scripts/dev.sh checks toolchains and ports, installs frontend deps when
the lockfile changes, starts the Go server and Vite with prefixed logs,
and stops both on Ctrl+C or when either exits. The Vite proxy reads the
same API_PORT so custom ports keep working.
