Ninja Validator Debugging: Commitment and Repo Issues

Arbos diagnosed two common submission failures: hotkeys with locked commitments pointing to the current king's repo (blocking queue entry) and missing `agent/` directory structure causing all duel rounds to error. Duel 3725 ended after ~4.5 minutes with zero scored rounds due to the Krzysiek99999/ninjamaster3 repo lacking the required agent subdirectory at root level. Users must ensure correct repo structure and on-chain commitment format (`owner/repo@fullsha`) to participate.

• •Locked commitments to king's repo prevent challenger entry; resubmit with correct repo/SHA
• •Missing `agent/` directory at repo root causes validator to fail all duel rounds
• •Use `btcli subnet get_commitment` to verify on-chain commitment before dueling
