Initial commit: Feeds, an Android RSS reader

Feed subscriptions (RSS 2.0 + Atom, hand-rolled parser), OPML
import/export, WorkManager periodic fetch with conditional GET,
Room-backed local storage (feeds/articles/filter rules), keyword
mute/highlight filtering.

Reader mode: on-device extraction via Mozilla's Readability.js
(vendored from github.com/mozilla/readability, pinned to release
0.6.0) run in a hidden WebView, for feed articles whose provided
content is too thin to be the real article body.

Save: explicit action (from a feed article, or the Android share-sheet
target for any URL) archives to Stash via POST /artifacts?sync=true,
while a local on-device copy (Readability-extracted) is always kept so
saved articles read offline regardless of Stash's reachability.
