[FEATURE] No way to replay the onboarding tour once dismissed

[magic-peach]

Feature description
OnboardingTour.tsx sets a permanent localStorage flag (TOUR_KEY) on dismissal (line 261) with no UI anywhere to clear it and see the tour again.

Problem this solves
A user who dismissed the tour too quickly, or a returning user who forgot the shortcuts, has no way to revisit it short of manually clearing browser storage.

Proposed solution
A small "Replay tour" link/button, e.g. in the Footer or the Keyboard Shortcuts panel, that clears the localStorage key and re-triggers the tour.

Architecture notes

Reframe is a static Next.js app with output: "export". Key points:

• All video processing uses FFmpeg.wasm (client-side, no server)
• headers() in next.config.ts won't work — use vercel.json instead
• not-found.tsx requires public/404.html + vercel.json routes config

Happy contributing! ⭐ Star the repo if you find it useful!
