Pull request overview

This PR aims to increase mutation testing score (Issue #529) by adding/adjusting unit tests around ActiveRecord/ActiveQuery edge-cases (relations population/reset, upsert behavior, event dispatching, array access, etc.) and updating Infection configuration.

Changes:

Added new tests covering previously untested branches/edge-cases in ActiveRecord, ActiveQuery, EventsTrait, Arrayable/ArrayAccess traits, RepositoryTrait, and MagicActiveRecord behavior.
Introduced additional test stubs to exercise deep via() relations, event-enabled models, and ArrayAccess edge-cases involving name collisions between properties and relations.
Updated infection.json.dist to ignore several specific mutators/locations.

Copilot reviewed 13 out of 13 changed files in this pull request and generated 2 comments.

Pull request overview

This PR adds/extends PHPUnit coverage across ActiveRecord, ActiveQuery, events, array access/arrayable behavior, and several internal helpers to improve mutation score (Issue #529) by exercising previously untested branches and edge-cases.

Changes:

Added many new tests around relation population/reset, upsert/link/unlink edge cases, event dispatching, and query/join/via behaviors.
Introduced multiple new test stub ActiveRecord/ActiveQuery classes to support targeted scenarios (deep via relations, composite PKs, overridden internals, etc.).
Updated Infection configuration with explicit mutator ignores for specific survivors.

Doesn't it duplicate the next test?

Merged these checks into a single test: testModelRelationFilterUsesArrayOverlapsWithArrayValueAndColumnSchemaForArrayColumns, since both were covering the same ColumnType::ARRAY
