This PR improves Stylelint's performance when linting many files by reusing the cosmiconfig instance instead of creating a new one per file.
Previously,
getConfigForFile()created a new cosmiconfig instance for every call, losing the internal caching benefits that cosmiconfig provides. Now, the cosmiconfig explorer is created once increateStylelint()and stored on theStylelint instance as_configExplorer, allowing config discovery caching to be preserved across allgetConfigForFile()calls, and eliminating the overhead of repeatedly creating new cosmiconfig instances.Using the system benchmark tool and the main branch as the baseline:
