Fixed missing PlayOutcome.HIT_BY_PITCH handling in resolve_outcome().
HBP was being submitted via WebSocket but rejected with error:
"Unhandled outcome: PlayOutcome.HIT_BY_PITCH"
Changes:
- Added HBP case to play_resolver.py (lines 430-446)
- HBP uses same forced runner advancement logic as WALK
- HBP is NOT classified as is_walk=True (correct for stats)
- Added 2 unit tests: test_hit_by_pitch, test_hit_by_pitch_bases_loaded
Test results: 981/981 passing (100%)
