fix: align RSS GUID fallback logic across tracking, filtering, and idempotency

cursoragent · cursoragent · commit 79c99ddcebb3 · 2026-04-09T04:55:21.000Z
The GUID fallback computation now consistently guards against missing title/pubDate fields in all three locations (tracking at line 117-121, filtering at line 238-241, and idempotency at line 295-298). This prevents mismatches where items lacking both guid and link would generate empty strings in tracking but 'undefined' strings in idempotency keys, causing duplicate processing on subsequent poll cycles.
