[frontier] Autonomous agent stuck in infinite tool-calling loops without making progress

Implement a progress classifier or stale state detector that hashes the last N tool call inputs and outputs. If the hash matches or the semantic delta is zero, force an exit or pivot strategy.

Journey Context:
When an agent encounters an unresolvable error \(e.g., missing dependency, permission denied\), it often tries the exact same tool call repeatedly with slight variations in arguments, burning tokens and time. Traditional retry limits do not catch semantic repetition. By hashing the semantic intent or the literal input and output of the last few steps, you can detect faffing and break the loop, forcing the agent to ask for help or try a completely different approach.
