Subject: [PATCH] =?UTF-8?q?fix:=206=20UX=20regressions=20=E2=80=94=20popup?=

Cursor blinking (ACTUALLY fixed this time):
- handleFocus() was STILL missing due to botched duplicate removal in
  v1.12.1. Now defined once at line 80, no duplicates.
- vue-tsc --noEmit now runs clean (was erroring with TS2393)

Tool windows:
- App.vue now has onErrorCaptured + error display overlay so tool window
  crashes show the error instead of silently closing
- defineAsyncComponent uses object form with onError callback for logging

Selection highlighting:
- Changed from rgba(88,166,255,0.4) transparent to solid #264f78
  (VS Code's selection color) — always visible on dark backgrounds
- Applied to default theme, TerminalView applyTheme, LocalTerminalView

CSP:
- Simplified to 'self' 'unsafe-inline' asset: for default-src
- Separate connect-src for IPC protocols
