fix(cluster): add Muninn to SSH collection, fix ingest_corpus → glean_corpus rename

- Add [muninn] to NODES map in collect_cluster_logs.sh
  Muninn is accessible via WireGuard (ssh muninn).
  One-time 7-day backfill already gleaned: 262,659 entries.
- Fix broken script reference: ingest_corpus.py was renamed to
  glean_corpus.py — ongoing cluster glean was silently broken since the rename

scripts/collect_cluster_logs.sh
