[WIP] Add GitHub Actions workflow to run tests in next branch

[Copilot]

Adding GitHub workflow to run tests on the next branch

Plan:

• Explore repository structure and test setup
• Create GitHub workflow file (.github/workflows/tests.yml)
• Configure workflow to run on push, pull_request, and scheduled (daily)
• Set up PHP environment with appropriate versions (8.2, 8.3)
• Install composer dependencies
• Run PHPUnit tests
• Validate YAML syntax
• Add permissions block for security (CodeQL passed)
• Commit and push changes

Summary:

Successfully created .github/workflows/tests.yml that:

• ✅ Runs tests on every push and pull_request
• ✅ Runs tests daily via cron schedule (0 0 * * *)
• ✅ Tests against PHP 8.2 and 8.3 (matching the requirements of the next branch)
• ✅ Uses a matrix strategy to test multiple PHP versions
• ✅ Installs all necessary PHP extensions for Laravel/Backpack
• ✅ Runs composer test which executes PHPUnit with testdox output
• ✅ Has explicit permissions block (contents: read) for security
• ✅ No security vulnerabilities (CodeQL passed)

The workflow is minimal, surgical, and follows GitHub Actions best practices for Laravel packages. It addresses all requirements from the issue.

This section details on the original issue you should resolve

<issue_title>[Feature Request] The next branch needs a github workflow to run the tests</issue_title>
<issue_description>We are adding a few tests in the next branch, as you can see in this PR - #38

However, the tests aren't run on Github Actions so we can't follow if anything we do breaks the functionality or not. Also we can't see if the tests we are adding in the next branch are actually green or not.

Let's please start from the next branch and a github workflow, that would run those tests, Probably on:
push:
pull_request:
schedule:
- cron: '0 0 * * *' </issue_description>

<agent_instructions>Be as surgical as possible.</agent_instructions>
