Adjust shell analysis thresholds for better balance

Browse Source 
- Remove tolerance mechanism for strict occlusion detection
- Adjust visibility thresholds to balance shell preservation and internal deletion:
  - MIN_VISIBILITY_RATIO: 0.05 → 0.04 (4% visibility required)
  - MIN_VOTES: 2 → 2 (maintain 2 votes minimum)
  - HIGH_VISIBILITY_THRESHOLD: 0.25 → 0.20 (20% for KEEP)
  - MEDIUM_VISIBILITY_THRESHOLD: 0.08 → 0.06 (6-20% for REVIEW)
- Add Chinese comments for all shell analysis constants
