Add class keyword picker, alignas alignment picker with member realignment

Browse Source 
- Class keyword (struct/class/union/enum) persists in JSON, drives generator output
- CommandRow2 shows alignas(N) pill computed from struct member alignment
- Clicking alignas opens picker (1, 4, 8, 16) to realign all members
- Going up: members repositioned to N-byte boundaries, padding fills gaps
- Going down: excess padding removed, members pack tighter
- Add cmd::ChangeOffset for undoable offset repositioning
- All 11 tests pass
