Summary

• Show app and desktop plugin update indicators in Settings. Display app download progress while keeping the installed version visible, and preserve known updates when a background check fails.
• Keep the first app visible when a device connects. Use slim overlay scrollbars and consistent row padding without shifting the sidebar content width.
• Shorten Korean text across the shell and built-in plugins, with consistent wording and localization placeholders.

Changelog

Add update indicators and download progress in Settings, improve sidebar scrolling and spacing, and simplify Korean UI text.

Test Plan

• yarn typecheck, yarn test, and panel asset validation — passed.
• English/Korean localization key and placeholder checks — passed.
• Manual UI checks covered device connection scrolling, long and short sidebars, update indicators, an older desktop plugin updating to a newer release, and progress layout. Reviewed light and dark design examples.
• App installation and relaunch were checked manually; automated updater handoff and physical USB regression tests were not run.
