Custom matcher configuration for Jasmine 7.0.1

Goal: Determine whether a custom asymmetric equality tester written for Jasmine 6.x will function correctly under Jasmine 7.0.1 without modification.

Constraints: The project uses Node.js 14 and installs Jasmine via npm; the only published change between v6.3.0 and v7.0.1 is the version bump released on 15 Aug.

Specific questions:

• Does the jasmine.addMatchers API remain unchanged between v6.3.0 and v7.0.1?
• Are there any breaking changes to the expect extension mechanism that would affect custom matchers?
