misc: correct newline wrapping in logs for strings with ANSI codes

cli/CHANGELOG.md

 - Fixed an issue on Windows where extracting the Studio or Prompt bundle could fail with `EPERM: operation not permitted` when renaming extracted files. The extract step now retries on EPERM/EACCES with a short delay to handle transient file locks. Addressed in [#33330](https://github.com/cypress-io/cypress/pull/33330).
 
+**Misc:**
+
+- The Node.js path is now displayed correctly in run log headers for typical GitHub Actions paths. ANSI escape sequences are no longer incorrectly displayed for longer Node.js paths. Addresses [#32736](https://github.com/cypress-io/cypress/issues/32736).
