Summary

• Upgrade to Pest 5 and compatible plugins/Testbench; require PHP 8.4.1+ and Laravel 13 under owner authorization to drop older unsupported targets.
• Run stable and lowest dependencies on actual PHP 8.4, 8.5 and 8.6, with runtime assertions and fail-fast disabled.
• Restore Livewire test coverage, update closure assertions for PHPUnit 13, migrate the XML schema, and rename two unchanged serialization snapshots for the new runner.
• Leave production PHP behavior and Composer security blocking unchanged.

Verification

• Full suite passed locally across all six runtime/dependency combinations, including real PHP 8.5.12 and PHP 8.6.0-dev.
• Five rows: 1327 passed / 3619 assertions. PHP 8.6 lowest: 1318 passed plus 9 non-failing dependency deprecations / 3619 assertions. Existing 11 skipped and 1 todo retained.
• PHPStan, targeted PHP CS Fixer, actionlint, strict Composer validation, runtime mismatch checks, and clean-base patch application passed.
• Pest 5.3.5 currently caps PHPUnit at 13.4.5; forcing 13.4.6 would conflict.

Hosted CI verified on head a268756: all six test jobs passed in both the push run and PR run. Logs confirm actual PHP 8.5.12 and PHP 8.6.0-dev in both dependency modes, with the test counts above. PHPStan and styling also passed. No merge or deployment is requested.
