Pull request overview

Adds a new custom PHPStan rule to discourage brittle “assertSee”-style assertions in tests by flagging calls to the assertSee* / assertDontSee* family on known testing receivers, along with focused PHPStan-rule tests and fixtures to validate correct detection, exclusions, and inline-ignoring behavior.

Changes:

• Introduces CanyonGBS\Common\Rules\NoAssertSee\NoAssertSeeRule and registers it in phpstan-extension.neon.
• Adds a dedicated PHPStan config plus Pest-based rule tests that execute PHPStan against fixtures.
• Adds fixtures that exercise banned assertions, allowed lookalikes, and identifier-based inline ignores.
