Move build resources to resources/build/, icon source files to
resources/icon-source/, scripts to config/scripts/, and patches

- Move xterm FitAddon refresh() outside the resize conditional so
sub-cell-width container shrinks don't leave blank content
- Defer startup notification to window 'show' event so the macOS
permission dialog appears after the window is visible
- Add click handler on startup notification to open System Preferences
- Prevent GC of startup notification via activeNotifications set
- Fix lint-staged config: remove yaml/html/md from oxfmt pattern
since oxfmt only supports json and css beyond JS/TS
Patch @xterm/addon-fit to refresh the full viewport and restore scroll
position after reflow, batch ResizeObserver through requestAnimationFrame
to coalesce rapid-fire reflows, and recover terminal rendering after
WebGL context loss.
