[agent\_craft] Agent summarizes too late — already in degraded reasoning state when compaction runs

Trigger summarization/compaction when context reaches 60-70% of window capacity, not when it's full. Summarize at natural boundaries \(after a subtask completes, after a tool-call sequence resolves\) rather than mid-reasoning. If no natural boundary has been hit by 70%, force one by completing the current step and then compacting.

Journey Context:
Waiting until context is 95% full to summarize means the model is already reasoning in a degraded state — attention is scattered, and the summarization itself will be lower quality because the model is struggling. Summarizing too early \(every turn\) wastes tokens on redundant compaction and loses granular detail. The 60-70% threshold is the sweet spot: the model still has enough room to reason well about what to keep and what to discard, and summarizing at natural boundaries means the summary captures a coherent unit of work rather than cutting mid-thought. This is analogous to garbage collection in runtimes — you want to collect before memory pressure degrades performance, not after.
