Type the queue mock against the Queue contract.

Queue is imported from @cloudflare/workers-types, and its send and sendBatch methods return Promise<void>. MockQueue currently defines synchronous methods with narrower, hand-written parameter types. The as unknown as Queue casts bypass both checks at all three construction sites. Type MockQueue from Queue and remove the double casts so the test mock remains aligned with the Cloudflare Queue API.

In `@packages/cfworkers/src/mod.test.ts` at line 398, Update MockQueue to
implement or derive its method signatures from the imported Queue contract,
including Promise<void> returns and matching send/sendBatch parameter types.
Remove the unknown-as-Queue double casts at all three WorkersMessageQueue
construction sites so TypeScript validates the mock directly.

@whangsg Please address this by typing MockQueue against the imported Queue contract and removing all three as unknown as Queue casts. The casts currently hide actual type mismatches.

One correction to the review: the PR's locked @cloudflare/workers-types@4.20260511.1 declares send() and sendBatch() as returning Promise<QueueSendResponse> and Promise<QueueSendBatchResponse>, respectively, rather than Promise<void>. It also requires metrics(), and sendBatch() accepts an Iterable<MessageSendRequest<Body>>. Please use the imported types to keep the mock aligned with that version; making the existing methods return Promise<void> would not be sufficient.

The synchronous mock still allows the current payload-shape assertions to work, so this is a test maintainability concern. Please update the mock and rerun the relevant type checks and tests.
