Pull request overview

This PR refactors the build process for the @oxlint/plugins package to simplify the configuration and build steps. Instead of generating ESM and CommonJS builds into separate subdirectories (esm/ and cjs/) and then copying specific files, both builds now output directly to the same dist-pkg-plugins directory with different file extensions.

Changes:

• Configured TSDown to output both ESM and CommonJS builds to the same directory (dist-pkg-plugins)
• Added manual directory cleanup before TSDown runs, with clean: false in the config to prevent TSDown from deleting files between builds
• Simplified file copying to use a generic loop over all files instead of an explicit file list
