Module session 

Session-aware context buffer for cross-message privacy.

Tracks entities seen within a conversation session, enabling:

• Coreference resolution: “He” → PERSON_5 (from prior messages)
• Abbreviation matching: “TM” → ORG_7 (Tata Motors)
• Sensitivity escalation: decision-trace keyword detection
• Cross-message consistency: session-aware fuzzy matching with lower thresholds
