Subject: [PATCH] fix: WKWebView cursor/selection focus, theme restore on
 startup, status bar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cursor blink + selection (ROOT CAUSE FOUND):
- xterm.js v6 uses DOM renderer, not canvas. Cursor blink and selection
  both require CSS focus classes set by the hidden textarea's focus event.
- WKWebView doesn't focus elements with opacity:0, width:0, height:0,
  left:-9999em — the textarea never receives focus, classes never toggle.
- Fix: Override .xterm-helper-textarea to left:0, top:0, width:1px,
  height:1px, opacity:0.01 — within viewport, non-zero, focusable.

Theme restoration on startup:
- sessionStore.activeTheme started as null on every launch
- ThemePicker saved active_theme to settings but nobody restored it
- Added theme restoration to MainLayout onMounted — reads active_theme
  setting, fetches theme from backend, calls setTheme() before any
  terminals open

Status bar:
- h-10 (40px) to match toolbar height for visual balance

Selection colors:
- Solid #264f78 (VS Code selection blue) instead of rgba transparency
