FeedKeeper 0.26.6

A reader-quality release: pictures come in better, and a few things that never belonged in the article text are gone.

• Larger hero pictures: When a feed only offers a thumbnail of a picture (a size in the file name such as …__wide__148 or …-720x405.jpg) and the article shows the same picture in a clearly larger size, that size is now used, up to 2000 px wide. It applies to new items and as soon as an article's full text is stored.
• One badge instead of two: A link that holds a light and a dark variant of the same badge no longer shows both at full size in the reader. It keeps its label as text, and the publisher's call to action stays.
• No structured data in the text: JSON-LD that a page framework renders as an element of any name no longer shows up as article text.
• Dates and reading times: A line that is only a date or a reading time (15. Oktober 2026, 10:51 Uhr, 2 min, 4 min read) near the start of an article is dropped, since the reader shows both in its own head. The same lines further into the story stay.
• Dependency update: ipaddr.js 2.5.0 for the address check on feed hosts. It recognises more special-purpose ranges as non-public and treats short forms such as 127.1 as loopback; nothing that was blocked before is allowed now (#20).

No migration and nothing to do when upgrading.
