Replace the JSON-blob columns (feeds.articles, rules.affected_feeds) with proper relational tables: - articles(feed,key,…,is_read,grabbed) with UNIQUE(feed,key) and indexes, so dedup and grabbed become INSERT OR IGNORE / WHERE-key queries and a poll inserts only new rows instead of rewriting the whole feed blob. - rule_feeds(rule,feed) join table for a rule's feed scope. The webui RSS engine now operates on rows via a row-level store API (feed/article/rule/indexer upsert/list/etc.) instead of holding the feeds/rules/indexers in memory and saving whole lists; the in-memory copies and rss_save/rss_load are gone. The poller, the auto-download rules, force-run, manual download, refresh and search all read/write the DB directly. A one-time migration upgrades an existing webui.db in place (moving the old JSON blobs into the new tables, preserving article read/grabbed flags and rule scoping, then dropping the legacy columns).
