feat: M2 composite locator + idle reconcile
Refs #1
- observations: hcl backfilled from local rowid; (node_id, hcl) UNIQUE
locator index becomes the gossip merge key
- threads: cluster_key column + partial UNIQUE index; CreateThreadCluster
is idempotent, threader folds into exact cluster_key before heuristic
- AutoLinkThreadObservations dedup re-expressed on hcl DESC
- new `knox reconcile [--dry-run]` rebuilds entries from the observation
log and re-links threads idempotently (entry count, thread cluster_key
verified bit-identical from log-only DB)
