I discovered that none of the tests in this file were actually working — all of the client.on('spanEnd', ...) were never being called and since all the expects were inside of them nothing failed.
I have restructured the tests to make sure that if the events ever stop firing again in the future, the tests will fail, then fixed all the tests.

We can't reuse the port on each start since server.stop happens in the background and tests end up using each other's servers.

It turns out that the SDK initialised in here is effecting the SDK being used by bunserver.test.ts above. I am not familiar enough with the Sentry codebase to know how to properly reset after these tests but for sure something is missing here as the tests are not properly isolated.
I've had to add tracesSampleRate: 1 for now to ensure that the SDK being reused doesn't totally break the other tests which depend on tracing happening for every single call.

This is because the Bun instrumentation works by using `Proxy` on the call to `Bun.serve`, which isn't called for a reload. We can't wrap the serve created by calling `Bun.serve` with a `Proxy` as Bun seems to do some internal checks using `instanceof` which break if the instance is now reporting itself as a `ProxyObject`. This fixesgetsentry#15144.
