Subject: [PATCH] fix(codecov): leave `eval()`'d code out of coverage

Xdebug reports code run through `eval()` under the calling file's path with a suffix, so it passed the path-prefix filter and every report listed a source file that does not exist: on Windows its name turns into an NTFS alternate data stream, and Infection fails to resolve it from coverage-xml. Both drivers now drop the same pseudo-file names php-code-coverage skips.

Assisted-By: Claude Opus 5.5
