fix: disable native touch panning on mobile terminal and archive specs

- Change mobile terminal CSS to use touch-action: none and
  overscroll-behavior: none so the custom touch handler owns swipes
- Archive completed/partial OpenSpec specs to
  openspec/changes/archive/2026-06-14-completed-specs-archive/
- Regenerate project maps
