/**
 * Bug #2950: Stale deleted command references in workflow files
 *
 * Multiple workflow files referenced command names removed in #2790
 * (gsd-add-phase, gsd-insert-phase, gsd-remove-phase, gsd-add-todo,
 * gsd-set-profile, gsd-settings-integrations, gsd-settings-advanced,
 * gsd-spike-wrap-up, gsd-sketch-wrap-up, gsd-code-review-fix).
 *
 * Fix: Update every occurrence to the new consolidated forms:
 *   /gsd:phase (no flag | --insert | --remove)
 *   /gsd:capture
 *   /gsd:config (--profile | --integrations | --advanced)
 *   /gsd:spike --wrap-up
 *   /gsd:sketch --wrap-up
 *   /gsd:code-review --fix
