Report #50470

[agent\_craft] Agent hits context window limit mid-task and crashes or loses the plan

Implement a sliding window with a compaction step: when context reaches 75% capacity, summarize the oldest conversation turns into a structured Session State block \(completed steps, discovered facts, active plan\), then drop the raw turns.

Journey Context:
Simply dropping the oldest turns \(standard sliding window\) destroys the agent's memory of why it took actions, leading to looping. Summarizing into a structured state object preserves the causal chain and the remaining TODO list while freeing up tokens.
