Module history 

Conversation history management with forge-style compaction support

This module provides conversation history storage with intelligent compaction inspired by forge’s context management approach:

• Configurable thresholds (tokens, turns, messages)
• Smart eviction strategy (protects tool-call/result adjacency)
• Droppable message support for ephemeral content
• Summary frame generation for compressed history
