Probe Lopu conflict resolution (do not merge)

[lopugit]

Disposable live probe for the main→develop automation investigation.

This PR intentionally conflicts with the recently hardened README paragraph so the protected Lopu worker must perform a real model-backed conflict resolution. It will be closed and the branch deleted after the worker result; do not merge it.

Disposable live conflict probe complete: it proved the ordinary FIFO queue could delay the sync resolver, leading to the dedicated priority-lane fix in #510. Closing without merge and removing the probe branch as planned.
