Rebrand to FeeDreader; overflow-menu cleanup; deferred read-marking; folder-organized feed list

- Rename app to FeeDreader with an owl launcher icon and a paywall-avoidance
  note in Settings
- Move Open original/Save to Stash into the reader's overflow menu; add
  Mark unread there too
- Only mark an article read when navigating away via Previous/Next, not on
  open or on back
- Saved list no longer crosses out read items; its count includes them
- Back from Unread (the root screen) now opens the feed list instead of
  exiting the app
- Feed list: clearer separator above the per-feed list, folder grouping
  (from OPML categories) with case-insensitive sort, and a virtual "Last
  fetch failed" section at the top
- Reader extraction: cap unsized decorative SVG icons (fixes Ars
  Technica's giant section-badge icon), force native loading="lazy"
  images to load eagerly in the hidden extraction WebView, and drop a
  lightbox's duplicate caption only when a real figcaption sibling exists
- Backlog notes on swipe-to-next research, extraction test coverage, and
  an async-rendered-gallery race confirmed live on Ars Technica
