TextMimeData._normalizeLineEndings() converts bare LF to CRLF with a lookbehind regex, (?<!\r)\n. This replaces it with two plain string replacements: collapse every CRLF to LF, then expand every LF to CRLF.

The output is identical, including edge cases such as \r\r\n, lone \r and empty input. It is about 8x faster on typical text:

Input	Regex	replaceAll
100 KB	2.59 ms	0.34 ms
1 MB	24.55 ms	2.68 ms
5 MB	116.15 ms	14.18 ms
