…ation When color values contain CSS comments like 'rgba(255,0,0, /*alpha*/ 0.5)', the color interpolator would fail to parse them correctly, causing color transitions to not animate smoothly. This fix strips CSS /* ... */ comments from color strings before passing them to the color parser, allowing transitions to work even with commented color values. Fixes chartjs#12079

Summary
Fixes #12079
When color strings contain CSS-style comments (e.g.,
rgba(255, 0, 0 /* red */, 0.5)), the color interpolation during animation would fail because the color helper couldn't parse the commented string.Changes
stripCssCommentshelper function to remove/* ... */style comments from color stringsUse Case
Some users document their colors inline using CSS comments, which is valid CSS but wasn't being handled by Chart.js's animation system:
backgroundColor: 'rgba(255, 0, 0 /* red */, 0.5)'This fix ensures such colors can still be animated properly.
