`1.5.0` regression: workers treated as ESM by default

[declann]

Hi,

Glad to stumbled on this neat project and looking forward to using it to write more consistent browser-node code.

I'm trying to get duckdb-wasm working in node, I found a bare-node example in their repo.

It fails when I run it, with error:

ReferenceError: module is not defined

It uses web-worker, and it seems like the worker code (clearly CJS and with file extension cjs) gets detected like an ESM module.

Downgrading web-worker from 1.5.0 to 1.4.1 fixes the issue. I tried a few other things like passing type: commonjs, type: classic - none worked.

Suggests a regression in 1.5.0 release (edit: unless changing the default behavior in 1.5.0 is intentional)

Thanks
Declan
