- Changed context promotion to trigger on context overflow errors instead of a configurable threshold percentage. - Removed the contextPromotion.thresholdPercent configuration setting. - Updated context promotion to retry immediately on the promoted model without requiring compaction. - Refactored context promotion logic to attempt promotion before compaction in the overflow handling flow. - Updated agent session to merge context promotion checks into the compaction method for unified overflow handling. - Updated tests to reflect overflow-based promotion triggering instead of threshold-based promotion.
