Classify Inbox

Triage the inbox into buckets (default: recruiter_inbound, candidate_reply, cold_outreach_reply, spam) with a confidence per thread. Cache-first; repeat it to finish a large backlog (remaining).

Each thread is judged on its type (regular DM / inmail / sponsored / linkedin_offer), the sender's name and headline, the subject line if it has one, and the latest message. linkedin_offer threads are labelled spam with no model call (auto_labeled).

Args: taxonomy: optional custom list of labels to bucket into limit: max PROVIDER CALLS to spend this call, retries included (default 25). Keep it near 20 — the calls are sequential and a larger batch can outrun the client timeout. failed counts threads the model would not label.
