#13095 65e6684 Thanks @penalosa! - Reject V8 coverage provider with a clear error message
V8 native code coverage (@vitest/coverage-v8) requires node:inspector to collect profiling data from V8's runtime. workerd only provides node:inspector as a non-functional stub, so V8 coverage would silently fail or crash with a confusing No such module "node:inspector" error.
The pool now detects this configuration early — during Vite plugin setup, before Vitest tries to load the coverage provider — and throws a clear error directing users to use Istanbul coverage instead, which works by instrumenting source code at build time and runs on any JavaScript runtime.
