fix: image resize preview, todo checkbox alignment, modal overflow clip

- Image resize respects width attr in preview (no more snap-back)
- Single-task checkbox aligned with flex center instead of translateY hack
- Modal/detail containers clip card-bar at rounded corners
- Right-click on image no longer triggers resize (left-button only)
- Split dist.sh and bump.sh into separate scripts
