Bun crash on windows symlink code files

[pragmatta]

How can we reproduce the crash?

1. Use windows and bun v1.1.44-canary.30
2. Use codefile project root that is an absolute symlink to elsewhere
3. Include the code file as import { foo } from "./codefile"

Problem can be worked around by switching symlinks to junctions, but that's not a really good solution.

I'm pretty sure #16621 fixed this. Let me know if its still an issue for you.
