docs: update comparison table with accurate mem0 features

- Add 'Pure openmemory MCP' column to differentiate from SDK usage
- Correct mem0 auto-extraction: has infer=True but requires add() call
- Correct mem0 PII detection: partial support exists
- Add ROT cleanup and Ebbinghaus decay rows
- Add 'Key Differences' section comparing OMP vs pure openmemory
- Sync changes to both Chinese and English README
