FilesystemBackend.grep silently degraded to its slow Python fallback whenever ripgrep wasn't on PATH, timed out, or errored, leaving operators unable to diagnose why searches were slow or returning suspicious zero-match results. The change adds targeted logs for each failure mode and stops treating ripgrep hard errors (rc ≥ 2) as "no matches".
