Merge main into massive-terminal-upgrade

Resolves merge conflicts:
- apps/server/src/routes/terminal/common.ts: Keep randomBytes import, use @automaker/utils for createLogger
- apps/ui/eslint.config.mjs: Use main's explicit globals list with XMLHttpRequest and MediaQueryListEvent additions
- apps/ui/src/components/views/terminal-view.tsx: Keep our terminal improvements (killAllSessions, beforeunload, better error handling)
- apps/ui/src/config/terminal-themes.ts: Keep our search highlight colors for all themes
- apps/ui/src/store/app-store.ts: Keep our terminal settings persistence improvements (merge function)
