Suppress errcheck warnings for calls where the return value is safely
ignored:
- resp.Body.Close() (artifacts/client.go): deferred cleanup — failure
to close a response body is non-critical; the defer itself is what
matters for connection reuse.
- rows.Close() (bundle/exporter.go): deferred cleanup in a loop where
rows.Err() already handles query errors.
- filepath.Walk (bundle/exporter.go): top-level walk call; errors in
sub-directory traversal are handled by the inner callback (which
returns nil for err != nil).
- broadcaster.RecordAndBroadcast (bundle/importer.go): fire-and-forget
event broadcast; errors are logged internally by the broadcaster.
- db.DB.ExecContext (bundle/importer.go): best-effort runtime column
update; non-critical auxiliary data that the provisioner re-extracts
if needed.
Fixes: #1143
