docs: add redamon.org/docs canonical banners + XBEN 8/16-20 walkthrough videos Prepend a canonical banner to each curated wiki page linking to its version on the official docs site (redamon.org/docs), so search engines consolidate authority onto the owned domain instead of ranking the GitHub wiki. Also adds the walkthrough video links to XBEN-008/016/017/018/019/020 in the benchmark table.
