Bulk-archive (soft-delete) API-origin skills. Always a bulk operation: send an
items array (1–100 items). Each item is resolved by its /skill/source +
/skill/externalId locator. Archiving applies only to skills created via this
public API; a locator that points to a non-API-origin skill is reported as not
found. Per-item results are returned in results; the request returns 200
even when some items fail.

Rate limit: 10 requests/min per tenant.

OAuth scope (app-user): job_catalog.skills:write.

IAM permission: Job catalog / Skills / Manage (company-scoped).
