Reverted static/hyperscript/functions._hs to the working version that
eliminates the "Expected 'end' but found 'def'" parse error.
The issue was caused by the expanded version with toggle functions.
The working version (133 lines) from commit 1f7757c has the simpler
structure that hyperscript 0.9.12 can parse correctly.
Verified with comprehensive browser testing:
- No parse errors in browser console
- Scroll behavior works correctly
- Back-to-top button shows/hides as expected
- All hyperscript functions load successfully
