- Add IconRss component and feedHref prop to ListToolbar
- Wire feed links on Nodes, Advertisements, and Messages pages
- Messages feed link respects channel filter, defaults to idx 17
- Simplify advert/node feed item bodies, link adverts to packet hashes
- Add unit tests, page tests, and e2e specs for feed link behavior
Four feeds (public messages, node adverts deduped per node, new nodes,
per-community-channel messages), each in RSS 2.0 and Atom, built with
stdlib ElementTree. Feeds are hard-pinned to the logged-out view
(anonymous visibility, spam always filtered, identity headers ignored)
and served at clean public web URLs (/feeds/*) via a shared proxy helper
that forwards If-None-Match + X-Forwarded-* and gates on maintenance
mode. Responses are Redis-cached (ETag/304, public max-age) and
invalidated with messages/adverts/channels mutations. Item/self links
always target the public web endpoint; WEB_PUBLIC_URL pins the canonical
origin. Includes a FEATURE_FEEDS kill switch, SPA autodiscovery <link>
tags, and env/docs updates (v0.21.0 upgrading notes).
