feat(angular): Add support for zoneless change detection in Angular 20

[AtofStryker]

Current Behavior

Currently, @cypress/angular does not support zoneless change detection which will be the default in Angular 20.

Desired Behavior

Add support for zoneless change detection in @cypress/angular to align with Angular 20's new defaults.

Related Issues

• Related to Cypress component tests not working without zone.js #30070 (Angular zoneless change detection)
• Part of Cypress 15 release breaking: 15.0.0 Release #31408

Technical Details

• Angular 20 is introducing zoneless change detection as the default
• This change is part of Angular's move away from zone.js
• The implementation should support both zoned and zoneless applications

Implementation Considerations

1. Support for manual change detection triggering
2. Integration with Angular's new test runner
3. Backwards compatibility for applications still using zone.js
4. Documentation updates for both zoneless and zoned testing approaches

Questions

• How should we handle the transition period where both zoned and zoneless applications need to be supported?
• What are the implications for existing test suites?
• Should we provide migration guides for users moving from zoned to zoneless testing?

Additional context from this article:

This change aligns with Angular's move towards zoneless change detection as the default in Angular 20, which makes this support important for the Cypress Angular component testing implementation.
