Fix CRLF line break cleanup before source map annotations - #2187
The empty-processor path removes LF characters before a source map annotation but leaves the CR half of CRLF behind. For example, processing a{}\r\n/*# sourceMappingURL=a.map */ leaves a{}\r.
Include CR in the line-break cleanup, while preserving the original whitespace when it separates content after the removed annotation. This keeps a\r\n/*# sourceMappingURL=a.map */b{color:red} as a descendant selector instead of joining it into ab.
The regression tests cover LF, CRLF, and CR at EOF, multiple annotations, and selector separators. Validation: 745 unit tests passed, along with lint, type, version, coverage, and size checks.
Summary by CodeRabbit
Bug Fixes
Source-map annotation cleanup now handles LF, CRLF, and CR line endings. It removes surrounding line breaks when an annotation ends the CSS or is followed by whitespace, while preserving line breaks that separate selector fragments or precede an annotation followed immediately by other content. This prevents adjacent CSS tokens from being unintentionally joined during cleanup.
No actionable comments were generated in the recent review.
Walkthrough
clearAnnotation now removes preceding line breaks only when an annotation ends the CSS or is followed by whitespace. Tests cover LF, CRLF, and CR input, including cases where line breaks must remain between selector fragments.

clearAnnotation checks whether an annotation ends the CSS or is followed by whitespace before removing preceding \n and \r characters. Tests cover LF, CRLF, and CR input, including preservation of selector separators.

- Line 90: The annotation-removal logic around the `this.css[startIndex - 1]`
check can remove a required CSS separator; preserve the separator when following
CSS needs it so removing the source map annotation does not merge tokens. Add a
regression test for `map: false` with `a\r\n/*# sourceMappingURL=a.map
*/b{color:red}` that verifies the selector remains separated.
