chore: require validators 0.6

[ChiragAgg5k]

Summary

• narrow the validators dependency from 0.* to ^0.6
• raise the minimum and CI PHP version to 8.5, matching validators 0.6

Dependency order

This PR remains a draft until the validators 0.6 updates for console, servers, domains, and their dependent packages are released. The lock file will be refreshed after those releases so Composer can resolve the full dependency graph.

Greptile Summary

The PR raises the package’s minimum PHP version to 8.5 and updates the validators dependency to the 0.6 release line.

• Updates the Composer manifest and lock file for PHP 8.5 and validators 0.6.
• Aligns the documented PHP requirement with the manifest.
• Removes PHP 8.4 from the CI test matrix.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains within the scope of this follow-up review.

The previously reported mismatch is fixed: README.md now documents PHP 8.5 or later, matching the manifest requirement.
