Add dancer Easter egg

[Huxpro]

Summary

• add a hidden quick double-tap trigger on the 好忙啊 subtitle
• animate an original 16-frame BusyWeek mascot at 12 fps directly inside the existing timeline
• use measured row offsets and Todo text widths to route each real Todo line around per-frame Pretext exclusion geometry
• keep the original renderer measurement nodes mounted so row heights, Todo identity, controls, and scroll position remain stable
• preserve Todo state while supporting background pausing, teardown, reduced motion, and immediate dismissal by a second trigger
• document the generated asset provenance and bundle impact

User impact

The Easter egg now demonstrates the powerful path requested in #9: the dancer occupies the live Todo-list area and the actual Todo text flows around its changing silhouette. It does not recreate or overlay a decorative copy of the list, and it never mutates Todo data.

Validation

• npm run build (Web and Lynx native)
• node --test tests/*.test.ts (112 passing)

Closes #9
