Niklas MischkulnigandGitHub 6e894d0511 Turbopack: respect the module-sync export condition (#93970)
I set it to `::Unknown` because we the runtime may or may not support
module-sync. So let's just trace both for now



There is one problem though:


https://nodejs.org/docs/latest-v26.x/api/packages.html#conditional-exports
> "module-sync" - matches no matter the package is loaded via import,
import() or require(). The format is expected to be ES modules that does
not contain top-level await in its module graph - if it does,
ERR_REQUIRE_ASYNC_MODULE will be thrown when the module is require()-ed.

So we have multiple options:
1. We definitely want to respect module-sync for tracing. We don't
really have to throw ERR_REQUIRE_ASYNC_MODULE here, Node.js will do it
at runtime anyway.
2. ~~What about bundling? Either~~
- ~~Respect module-sync always, but don't throw
ERR_REQUIRE_ASYNC_MODULE.~~
- ~~Respect module-sync always, and do throw a build error the module
requires TLA. This would require a separate validation pass though.~~
   - I'm not enabling it for bundling for now
