Subject: [PATCH] feat(export): modernize export panel and ai harness

- Modernize ExportPanel with preview-first UX, format cards, and scope selection.
- Update AIHarness with a lab-ready four-panel layout and truthful status.
- Refactor JobMetrics to use tokenized CSS and gate to development mode.
- Update styling to align with 2026 UI modernization tokens.
- Ensure compliance with anti-slop rules for local-first messaging.
