Description
tinybench@2.9.0 narrows the inherited EventTarget listener signatures in its
published Task and Bench declarations. Those overrides are incompatible with
the generic EventTarget emitted by wrangler types for Workerd.
Minimal reproduction:
https://github.com/screenfluent/upstream-type-repros/tree/2b0ff6d355a8631199c2d6cbe45f397f472ae222/tinybench-workerd
Actual result
TS2416: Property 'addEventListener' in type 'Task' is not assignable to the
same property in base type 'EventTarget<Record<string, Event>>'.
Type 'string' is not assignable to type 'TaskEvents'.
The same failure occurs for Task.removeEventListener and both methods on
Bench.
Expected result
The Tinybench-specific overloads should preserve a fallback signature compatible
with the inherited EventTarget contract.

Is Workerd's generic EventTarget intended to be supported, or should this
compatibility be handled downstream?
