This commit enhances the jasmine-vitest schematic by adding mock names to `vi.fn()` instances created from `jasmine.createSpyObj`. This improves debugging in Vitest by providing meaningful names for mock functions, making test failures easier to understand and trace.
This commit adds a safety check to the `done` callback transformation in the `jasmine-vitest` schematic. Previously, if a `done` callback was used in an unhandled way (e.g., passed as an argument to a helper function), the schematic would remove the `done` parameter but leave the usage, causing runtime errors. Now, the transformer counts the total usages of the `done` callback and compares it to the number of usages it successfully transformed. If there are unhandled usages, it aborts the transformation for that specific test and adds a TODO comment, ensuring that no broken code is generated.
…Contents This commit improves the transformation of `jasmine.arrayWithExactContents` in the `jasmine-vitest` schematic. While Vitest does not have a direct equivalent for multiset equality, the schematic previously transformed this into a check for length and subset containment, which could lead to false positives (e.g., `[1, 1]` matches `[1, 2]`). Now, the schematic attaches a TODO comment to the generated code, explicitly warning the user that the transformation relies on `expect.arrayContaining` (a subset check) and advising them to verify strict content matching manually.

This is how you do the same in Jest/Vitest:

| expect(myArray).toEqual(['a', 'b']); |

That's not equivalent. The following passes but would fail with that transformation:
expect([1, 2]).toEqual(jasmine.arrayWithExactContents([2, 1]))
