Evaluate dependency version fixes and importer patches for FX compatibility

[atebites-hub]

If the failure is due to dependency version mismatch (PyTorch, torchdynamo, TVM), evaluate minimal version pin changes or apply small patches to the TVM Relax importer to accept newer FX types. Prefer importer-side fixes and shims over major dependency upgrades. Document rationale and results.

Hi team! 👋 I've opened a PR to address this: #20

This update resolves the FX compatibility issue by adding a few targeted patches to the TVM Relax importer. Instead of bumping core dependency versions, the PR introduces lightweight shims that gracefully handle newer FX types, keeping our environment stable while fixing the runtime mismatch. I've also documented the rationale and testing results in the PR description.

Let me know if you have any questions or feedback—thanks! 🚀
