 Polling and announcements:
 
 - Alerts are polled every 5 minutes by default
 - On `add`, existing results are recorded without announcing (prevents flood)
 - New results announced as `[name/<tag>] Title -- URL` where tag is one of:
-  `yt`, `tw`, `sx`, `rd`, `ft`, `dg`, `gn`, `kk`, `dm`, `pt`, `bs`, `ly`, `od`, `ia`

+  `hn`, `gh`
 - Titles are truncated to 80 characters
 - Each platform maintains its own seen list (capped at 200 per platform)
 - 5 consecutive errors doubles the poll interval (max 1 hour)
