- replace http.DefaultClient with a 60s-timeout client and send a
User-Agent header
- retry 5xx and transport errors with the same ctx-aware backoff used
for 429s; drop the unreachable trailing return and defer-in-loop body
- resolveUser returns the username; posts carry the handle (was numeric
ID), error on 200-with-empty-data, and skip empty-ID tweets
- remove the lower limit floor so small limits pass through
- AGENTS.md: refresh the stale twitter clamp/backoff gotcha
