feat: support yielding intercepted calls

[cayasde]

What changed

• Allow mock.capture, mock.respond, and mock.release to wait through yields from the controlled callback or released original method.
• Add coverage for yields before capture, between captured calls, after release, and asynchronous callback errors.
• Document the yielding contract and add a minor Changeset.

Why

Tests must be able to control code that legitimately uses task.wait() without replacing its timing behavior through dependency injection.

Impact

Controlled interception operations can now yield when the code under test yields. Test runners must support yielding tests in those cases.

Validation

npm run check

npm test
