Run UX: when start_run throws before/around launch (e.g. ENOSPC creating the temp dir — the box is out of disk), the run was marked "failed" with empty output. Now the exception is broadcast + written to the run output/results so the run view shows e.g. "[run error] OSError: [Errno 28] No space left on device" instead of a blank failure. Widget audit follow-ups (no broken links were found; these are consistency): - host_resource_history widget now charts root (/) disk, consistent with the host panel (was the opaque "disk worst"). - host_resources widget: tooltip on the health dot explaining it warns on the worst mount while the number shows root. - status_overview widget detail_url /status → /status/ (avoid redirect). - Normalize ad-hoc widget empty-states to the shared .empty style (wording, which distinguishes "configured" vs "data yet", preserved).
