Vijay Janapa Reddi d8a3ee0837 Remove unnecessary matplotlib import from losses module

Issue: xor_crisis.py was failing with ImportError on matplotlib architecture mismatch
Root cause: losses_dev.py imported matplotlib.pyplot but never used it

Fix:
- ✅ Removed unused imports: matplotlib.pyplot, time
- ✅ Re-exported module 04_losses to update tinytorch package
- ✅ Verified both milestone 02 scripts now run successfully

The matplotlib import was causing failures on M2 Macs where matplotlib
was installed for wrong architecture (x86_64 vs arm64). Since it was
never used, removing it eliminates the dependency entirely.

Tested:
- ✅ milestones/02_xor_crisis_1969/xor_crisis.py (49% accuracy - expected failure)
- ✅ milestones/02_xor_crisis_1969/xor_solved.py (100% accuracy - perfect!)
