Pull Request Overview
This pull request changes the default value of output.generatedCode.profilerNames from a dynamic value based on minification settings (!minify.is_enabled()) to a static false value. The change aims to make the output more suitable for libraries, as profiler names make the code harder to minify.
Key changes:
- Changed Rust default from
!raw_minify.is_enabled()tofalse - Updated TypeScript documentation to reflect the new default and add a warning
- Added comprehensive documentation explaining why profiler names should be avoided for libraries
- Updated 261+ test snapshots to reflect the new default behavior
