Cypress 15: Breaking changes #30767

Checklist

Before merging `release/15.0.0` into `develop`

Make sure all npm packages with breaking changes run against npm-release CORRECTLY in circle CI and calculate the correct version. This is critical to make sure breaking changes to the npm packages are applied or else rolling back is incredibly difficult. Do a dry run once ready to make sure major versions are applied to:
- @cypress/angular has a breaking change that should publish version 4.x.x
- @cypress/webpack-dev-server has a breaking change that should publish version 5.x.x
- @cypress/webpack-preprocessor has a breaking change that should publish version 7.x.x
- Test the Cloud project on the binary https://github.com/cypress-io/cypress-services/issues/9730
The following packages are removed and need to be deprecated in npm
- @cypress/angular@3 is deprecated but the package is not. we just need to mention we do not support this in the migration guide which is covered in https://github.com/cypress-io/cypress-documentation/pull/6159/files?
Run the 15.0.0 branch against cypress-services repo (especially with Protocol, Studio, etc relying on the Cypress object) - check Cypress.SelectorPriority change.

After merging `release/15.0.0` into `develop`

Make sure all npm packages with breaking changes are published as breaking changes:
- @cypress/angular should publish 4.x.x
- @cypress/webpack-dev-server should publish version 5.x.x
- @cypress/webpack-preprocessorshould publish version 7.x.x
- @cypress/webpack-batteries-included-preprocessorshould publish version 4.x.x
  - [] update cypress-example-recipes to use the latest @cypress/webpack-batteries-included-preprocessor and configure the crypto built-in. See chore: add minimal built-ins back in to @cypress/webpack-batteries-included-preprocessor #31815 (comment)
- Make sure to remove the pull_request_id from cypress-example-recipesinside cypress-io/cypress and merge in chore: use cypress 15 prebuilt binary and test built-in shimming cypress-example-recipes#921
We need to make sure synk jobs now run on node X and not node X

Release day

Coordinate cypress-services release (for Cypress.SelectorPlayground change in Studio Cloud?)
Deprecate the @cypress/angular--??? package.
After binary is deployed to dev tag (step 10), create a PR into cypress-component-testing-apps to bump all examples to use Cypress 15. While doing this:
- Remove references to cypress/angular????? and update them to cypress/angular. smoke test the projects affected
After binary is deployed to dev tag (step 10), create a PR in component-testing-quickstart-apps to bump all projects (4 in total) to use Cypress 15.
Merge Docs PR
Publish Cypress Blog (ping @jennifer-shehane to do this)
Ping Social Media to begin promotion (ping @jennifer-shehane to do this)

Please add to the scope under "Component testing":

Add support for zoneless change detection in @cypress/angular for Angular 20 (feat(angular): Add support for zoneless change detection in Angular 20 #31504) - This is needed as zoneless change detection will be the default in Angular 20 and is related to Cypress component tests not working without zone.js #30070.
