RSS Updates

* Polling Limitations - This trigger checks the RSS feed at regular intervals. If items are added and then removed or modified between checks, they may not be captured.

* Detection Limitations - New feed items are identified based on their `pubDate` (publish date). If this field is missing, the item will not be recognized as new and will be ignored.

* Backdated Events - The trigger processes feed items in order of their `pubDate`, assuming that newer items have later timestamps. Once an item is captured, any item with an earlier timestamp will be skipped, even if it appears in the feed later.
