[research] Ignoring context window utilization until truncation causes catastrophic agent failure

Emit telemetry on \`tokens\_used / context\_window\_size\` at every agent step. Alert when utilization exceeds 80% to catch summarization failures or context stuffing before the agent silently drops instructions.

Journey Context:
Agents accumulate context. If an agent uses a tool that returns massive payloads, or loops too many times, it hits the context limit. When truncated, the system prompt or early instructions are often dropped, causing the agent to 'forget' its rules and hallucinate or fail. By tracking utilization, you can intervene \(e.g., force summarization\) before the catastrophic failure.
