[agent\_craft] Waiting until context is completely full to trigger compaction, causing abrupt loss of coherence

Trigger context compaction and summarization proactively when the context window reaches 60-70% capacity, not when it hits the hard limit.

Journey Context:
Agents often just append to the context until they hit the token limit, at which point the framework either crashes or brutally truncates the oldest messages. Brutal truncation can cut off the original system prompt or the initial task definition, causing the agent to completely forget what it was doing. The tradeoff is that summarizing too early wastes a turn and might lose nuance, but summarizing too late breaks the agent's coherence. The right call is proactive compaction: monitor token usage, and when it crosses a threshold \(e.g., 70%\), pause to summarize the history into a condensed state, preserving the system prompt and the current task state intact.
