jedarden 3a3f376025 feat(pdftract-522li): implement per-thread cycle detection for object resolution 
Add thread_local HashSet<ObjRef> tracking for circular reference detection
in the Object Parser. This prevents infinite recursion when PDF objects
contain circular references.

- Created cycle.rs module with RESOLVING thread_local storage
- ResolutionGuard RAII ensures cleanup on drop (even on panic)
- is_resolving() helper for cycle detection
- All 13 cycle tests pass

Closes: pdftract-522li
