Support PHPUnit 13

See also https://phpunit.de/announcements/phpunit-13.html.

To Do

• Wait for upstream support
  • https://github.com/paratestphp/paratest/releases/tag/v7.18.0
  • Pest; see https://github.com/pestphp/pest/blob/4.x/composer.json#L33
• Look for further required changes; see also [8.x] Support PHPUnit 12 #325

@jnoordsij Any updates on this?

Currently Pest seems to block installing this here; see https://github.com/pestphp/pest/blob/4.x/composer.json#L33. There might be even more upstream limitations.

I've submitted a PR on the Pest side to unblock this:

• Pest PR: Support PHPUnit 13 pestphp/pest#1629 — widens Pest's PHPUnit constraint to ^12.5.8 || ^13.0
• Pest Issue: tracking PHPUnit 13 support

Breaking the circular dependency

The current blocker chain is:

1. Collision conflicts with PHPUnit ≥13.0.0
2. Collision's CI uses Pest, which also doesn't support PHPUnit 13
3. Pest requires collision, which conflicts with PHPUnit 13

The Pest PR breaks this from the Pest side. Once merged, collision can:

1. Update the conflicts section to allow PHPUnit 13
2. Run CI with PHPUnit 13 using Pest (once Pest releases with the change)

Interim suggestion for this PR

Since Pest is only a dev dependency of collision, this PR could also decouple the PHPUnit 13 CI from Pest:

• Add a CI matrix job that runs collision's PHPUnit integration tests directly with PHPUnit 13 (without Pest)
• Keep the existing Pest-based CI for PHPUnit 12
• This allows merging collision's PHPUnit 13 support without waiting for the full Pest release

The runtime code changes in this PR can be validated independently of Pest.
