Minor Changes

• #4949 40c3c87 Thanks @fubhy! - Added Random.fixed to create a version of the Random service with fixed
  values for testing.

• #4949 ed2c74a Thanks @dmaretskyi! - Add Struct.entries function

• #4949 073a1b8 Thanks @f15u! - Add Layer.mock

  Creates a mock layer for testing purposes. You can provide a partial
  implementation of the service, and any methods not provided will
  throw an UnimplementedError defect when called.

  import { Context, Effect, Layer } from "effect"
  
  class MyService extends Context.Tag("MyService")<
    MyService,
    {
      one: Effect.Effect<number>
      two(): Effect.Effect<number>
    }
  >() {}
  
  const MyServiceTest = Layer.mock(MyService, {
    two: () => Effect.succeed(2)
  })
