Greptile Summary

This PR upgrades utopia-php/domains from 3.0.0 to 4.0.0 and refreshes the Composer lock metadata.

• Keeps the dependency compatible with the repository’s PHP 8.5 and Validators 0.6 constraints.
• Introduces mandatory curl, mbstring, and SimpleXML platform requirements that are not currently documented or validated by CI.

Confidence Score: 4/5

The dependency upgrade appears safe to merge, with a non-blocking documentation and CI coverage gap around its new PHP extension requirements.

No API or dependency-resolution failure was established, but the upgrade introduces mandatory extensions that the documented system requirements omit and current CI installations explicitly bypass.

Files Needing Attention: composer.lock

Important Files Changed

Filename	Overview
composer.json	Updates the Domains dependency constraint from ^3.0 to ^4.0.0; its declared constraints remain mutually compatible.
composer.lock	Locks Domains 4.0.0 and records three new required PHP extensions that are not reflected in project documentation or platform validation.

### Issue 1
composer.lock:2009-2011
**Undocumented Extension Requirements**

Domains 4.0 now requires curl, mbstring, and SimpleXML, but the README still lists PHP 8.5 as the only system requirement, and CI installs dependencies with `--ignore-platform-reqs`. If a consumer uses a minimal PHP installation without one of these extensions, installation will fail without the project’s validation catching it. Please document the new requirements and validate at least one install without bypassing platform checks.
