ci-log drove only the live run-view streamer (POST .../runs/<n>/jobs/<j>
with logCursors), which reads the live act_runner task record. Forgejo
prunes that record once a run completes, so the streamer 500s with
'task ... resource does not exist' on quick or older runs even though
the web UI still shows the logs — the reader (argus, atlas) then had to
ask the operator to relay the error.
Add a fallback: when the streamer errors or returns no lines, download
the persisted whole-job log via the same web route the run page's view-
raw-logs link uses, .../runs/<n>/jobs/<job>/attempt/<a>/logs, keyed by
the per-repo run number with the attempt segment. It survives the task
prune. Live and recent runs keep the rich per-step streamed view; only
the pruned case takes the flat fallback (where --step can't apply). New
--attempt flag (default 1) selects the run attempt for re-runs.
Verified against a real pruned run whose streamer 500'd: the fallback
prints the full persisted log; a completed short job ends cleanly at
'Job succeeded', confirming the route returns complete logs.
