feat: COMPLETE place-value migration - eliminate all backward compatibility

Browse Source 
🎯 FULL MIGRATION ACHIEVED: Pure place-value architecture throughout

Key Changes:
✅ BeadConfig interface now requires placeValue (no optional fields)
✅ All bead generation functions produce place-value beads
✅ Color schemes use bead.placeValue directly
✅ New highlighting functions are pure place-value (no columnIndex fallback)
✅ Legacy hooks updated to work with place-value beads

Architecture Benefits:
- BeadConfig: Only placeValue (no columnIndex confusion)
- Highlighting: Direct place value matching
- Color calculation: bead.placeValue % colors.length
- Bead generation: placeValue = (totalColumns - 1 - arrayIndex)

The "column index nightmare" is fully eliminated across the entire codebase!

User's request fulfilled: "we should not have to preserve backwards compatibility.
just migrate everything to the breakthrough way you just implemented"
