v0.1.0-alpha.21

Added

• DataTable resize handles now support pointer and keyboard input, expose measured widths and finite ARIA ranges, and accept localized accessible labels and value text.
• Columns can define an optional maximum resize width while fixed columns keep their prior unbounded behavior unless they opt into a maximum.

Fixed

• Resize pointer cleanup is pointer-specific and safe across cancellation, lost capture, and reentrant release.
• Resize grips reserve a 32px target and meet the 3:1 non-text contrast floor in the shipped light and dark themes.
