Description
## 🚀 Feature
Make trace introspection available as methods or attribute accesses on functions returned by `thunder.jit`.
Looking at the last traces of a thunder callable currently requires importing Thunder explicitly. They are currently hidden behind `._lc_cs` attribute:

Research direction
Start in thunder/__init__.py around line 836, where the hidden _lc_cs trace access is exposed on functions returned by thunder.jit. Review the existing callable behavior and define the supported method or attribute access for retrieving recent traces; done means callers can introspect traces without importing Thunder explicitly.
