Bug fixes:
1. Wire is_published/mark_published/bump_last_seen into poll() loop
- Skip already-published items, bump TTL to prevent sweep
- Mark published after yield to track new items
2. Add conditional fetch support (If-Modified-Since, If-None-Match)
- Store Last-Modified/ETag from responses
- Send conditional headers on subsequent requests
- Handle 304 Not Modified gracefully (return empty list)
3. Document state parsing rationale in docstring
- Description has structured State: field vs unreliable title prefixes
Tests added:
- test_dedup_in_poll_loop: verify second poll yields 0 for same items
- test_conditional_304_yields_zero: verify 304 returns empty list
- test_conditional_headers_sent_after_first_poll: verify headers sent
