Create and crawl a managed knowledge website

Create the existing website group and enqueue its first crawl. Prefer this for multi-page websites with later refresh/selection management. Default depth two, maximum ten; page budget defaults/maxes to five hundred. Optional propertyId from list_properties, otherwise global. Return website.websiteId and job.jobId; use get_knowledge_crawl until terminal status, then get_knowledge_website and get_knowledge_usage. 202 means queued, not indexed/active. After an ambiguous failure discover the website/job before retrying. Required permission: knowledge:write. Connected business only; no tenant override.
