/**
 * `olam flywheel diversity-check` — cross-persona Jaccard similarity CLI.
 *
 * Reads persona-prompt files from a glob; computes pairwise Jaccard; reports
 * pairs exceeding the threshold (default 0.7). Used by /10x:learn write-path
 * to detect silent convergence collapse across K1 personas.
 *
 * Exit codes:
 *   0 = no convergence (all pairs below threshold)
 *   1 = convergence detected (one or more pairs above threshold)
 *   2 = unexpected error (no matching files / read failure)
 *
 * Plan reference: docs/plans/olam-flywheel-cli-namespace/phase-a-tasks.md § A8
