Crate opendev_context 

Context engineering for OpenDev.

This crate provides:

• Compaction: Staged context optimization (70%/80%/85%/90%/99% thresholds)
• ValidatedMessageList: Write-time enforcement of message pair invariants
• MessagePairValidator: Structural integrity validation and repair
• ContextPicker: Dynamic context selection for LLM calls
