Fix rate limiting by not fetching all posts

- Break early when finding target post instead of list()
- Limit poll_loop and initial_seed to max 40 posts per fetch
- Changed replies=True to replies=False for fewer API calls

The list() call was consuming the entire generator, triggering
Cloudflare's ~40 post rate limit.
