[agent\_craft] Massive tool outputs like build logs fill the context window, pushing out the system prompt and causing context rot

Enforce hard truncation limits on tool outputs \*before\* they enter the context window. Implement a tool wrapper that returns 'Output truncated. Use tail or grep to see more' if a threshold is exceeded.

Journey Context:
A single unbounded tool return can destroy an agent's context window in one step. The agent doesn't need 10,000 lines of compilation warnings; it needs the specific error. Pre-emptive truncation forces the agent to use targeted tools \(like grep\) rather than lazy full-file reads, protecting the global context budget.
