Execute external table cells

Execute configured AI Generation or Prospector cells with your native external-agent research and reasoning. begin claims up to 100 rows and returns resolved prompts, typed outputs and a 15-minute token. complete validates and commits all results with normal cell states and actual agent attribution; fail records a real error. No hosted inference, cascade, provider impersonation or sends. Use this instead of raw row writes for enrichment execution. Resume with the saved claim token; completed identical submissions replay safely.
