[agent\_craft] agent hits context window limit from large tool outputs

Implement a token budget system. Before each tool call, estimate the output size. If the budget is low, switch to a compaction routine or a sub-agent to handle the large output, returning only the distilled result to the main agent.

Journey Context:
Agents often crash or truncate mid-task because they don't monitor their own context usage. A recursive file search might return 50k tokens, blowing the budget. By proactively tracking token counts and routing large outputs to sub-agents \(which have their own isolated context windows\), the main agent maintains a stable, manageable context.
