+- `checkButtonWidthClasses`: false positive when `<!-- wp:button` appears on the same line as the outer `<div class="wp-block-buttons">` wrapper. The previous `str_contains` check matched `wp-block-buttons` as a substring of `wp-block-button`, incorrectly reporting missing `has-custom-width`/`wp-block-button__width-N` classes. Replaced with a word-boundary regex that distinguishes the singular `wp-block-button` (inner div) from the plural `wp-block-buttons` (wrapper).
