Remove unminified .min files.

[desrosj]

This removes the script-loader-packages.min.php and script-modules-packages.min.php files.

They were not being minified and an unminified vesion of the file is more human readable. The unminified file is roughly 10KB larger, which seems like a reasonable tradeoff.

Pull request overview

This PR removes the unminified “.min.php” package manifest files for script loader packages and script modules, consolidating generation and consumption to a single, non-suffixed PHP manifest file while still applying the runtime JS suffix (.min) when building script URLs.

Changes:

• Update tools/gutenberg/copy.js to generate only script-loader-packages.php and script-modules-packages.php (no .min.php variants).
• Update core loaders (wp_default_packages_scripts() and wp_default_script_modules()) to always include the non-suffixed manifest file.
• Adjust script module path handling so .min is appended at runtime (and VIPS modules always use .min.js).

Reviewed changes

File	Description
tools/gutenberg/copy.js	Stops generating *.min.php manifest files; writes a single manifest with .js keys.
src/wp-includes/script-modules.php	Loads a single manifest file and appends suffixes at runtime (with special handling for VIPS).
src/wp-includes/script-loader.php	Loads a single manifest file and derives handles/paths from .js keys plus runtime suffix.

• This JSDoc says the directory walk finds .asset.php files, but the code only matches entry.name.endsWith( '.min.asset.php' ). Please update the comment to reflect that only minified asset manifests are considered.

LGTM and tests well.

1. rm -rf gutenberg .gutenberg-hash; npm ci; npm run grunt clean:qunit; npm run build:dev
2. Review the files are generated in the assets directory as expected
3. Set define( 'SCRIPT_DEBUG', true );
4. Visit post editor, font library and site editor to ensure everything loaded as expected
5. Review scripts and styles in Query Monitor to ensure they're uncompressed versions
6. Set define( 'SCRIPT_DEBUG', false );
7. Visit same again
8. Review scripts and styles in Query Monitor to ensure they're compressed versions
