Supporting it.extend from vitest in effect/test

[tmcw]

What is the problem this feature would solve?

For our large test suite that tests a lot of CRUD operations, it's been pretty crucial to use automatic fixtures - a very fancy vitest feature. This makes it possible to test a CRUD operation that relies on a user object or some complex object already being initialized, and it does so in a way that doesn't require a lot of boilerplate per-test.

What is the feature you are proposing to solve the problem?

Ideally the effect/vitest module supports the .extend method. Currently it doesn't in Effect.

What alternatives have you considered?

I use vitest test context to manage PGLite instances for integration tests and that prohibits me from using the Effect vitest integration. There isn't really an alternative to test context for this because it can do "per worker", etc. which is vital for expensive resources like a PGLite instance.
