Execute a mobile-quick-plan. Reads a small mobile task plan (from chat or a /tasks/mobile-backlog/MOB-*.md file) and ships the code changes in one focused session. Lightweight pair to /mobile-feature — skips the ceremony that small mobile tasks do not need. Respects platform quirks (iOS/Android split files, native modules, simulator vs device), runs framework-specific verify commands (Metro, Flutter, xcodebuild, gradle), and ends with A/B choice: commit (A) or commit and push (B).
