…ion to retain NgZone.run

I observed that it chose to do this in one test.  These should not be removed
for libraries that support Zone applications and also should not be
removed for applications until the zoneless migration is entirely
complete.

Adds an ISO timestamp to the "Application bundle generation complete" message. This provides more precise information about when the build process finished, which can be useful for debugging and analyzing build performance.

Closes #30572

This commit removes an unused local variable.

…t-test

This commit refactors the Vitest test runner by extracting the complex plugin creation logic out of the main `VitestExecutor` class and into a dedicated `plugins.ts` module.

This change reduces the complexity of the executor, making it easier to understand and maintain. The executor is now more focused on its core responsibility of managing the test execution lifecycle.

Additionally, this commit introduces a `BrowserConfiguration` interface for better type safety and marks several executor properties as readonly to enforce immutability.

…ler modules

The main `application_builder.ts` file was becoming too large and difficult to navigate. This change extracts several logical components into their own dedicated files:

- Karma asset middleware
- Karma polyfills plugin
- Karma progress reporter
- Code coverage utilities
- Karma configuration helpers
- General utility functions

This improves the overall code structure, making it easier to understand, test, and maintain.

The main `initializeApplication` function within the Karma builder was overly large and handled several distinct responsibilities. This change refactors the function by breaking it down into three smaller, more focused functions:

- `setupBuildOptions`: Gathers and configures the esbuild build options.
- `runEsbuild`: Executes the esbuild build process.
- `configureKarma`: Sets up the Karma configuration based on the build output.

This decomposition improves the readability, testability, and maintainability of the Karma builder's application initialization process.

This commit refactors the unit test builder to centralize test file discovery, preventing redundant operations in the test runner's execution phase.

The `TestRunner` API has been updated to pass the test entry point mappings from the initial build options phase directly to the executor. This removes the need for the Vitest executor to re-discover tests, simplifying its logic and adhering to the DRY principle.

The JSDoc comments for the runner API have also been updated to reflect these changes.
