v0.10.0

Added

• In-app feedback / bug report: a "Send feedback" item in the user menu opens a
  form (type, subject, message) that emails all admins via the configured SMTP,
  with Reply-To set to the sender's account email. Off by default; admins enable
  it in Admin → Settings (requires SMTP).
• AI error badge: a red dot on the user menu and the Settings → AI nav item when a
  background AI call (e.g. scoring) last failed, so credit/quota errors are visible
  without opening Settings. Self-clears on the next successful AI call, or dismiss it
  manually via the × on the error panel in Settings → AI.
• Filter action archive: alongside label / mark-as-read / star, a filter can now
  archive matching articles (removes them from the inbox and exempts them from
  retention purge). Available in Settings → Filters and via OPML round-trip.

Changed

• Stats: the single "Backlog" figure is split into labeled backlog (unread items
  carrying a label) and starred backlog (your read-later pile); both are now
  all-time rather than capped at 90 days. Reading streak, per-day reads and the most
  active hour are computed in your own timezone instead of UTC.
• OPML import: Tiny Tiny RSS filter scope (feed / category) is now matched by name and
  mapped to the corresponding Readfine feed/folder scope, instead of being dropped and
  imported as global. Mixed scoped/global filters still import as global with a warning.
• Admin → Settings: the SMTP test now shows the underlying error detail on failure,
  making misconfiguration easier to diagnose.

Fixed

• Stats: corrected the engagement funnel bars.
• Mobile: the collapsible sidebar reliably reappears after a refresh instead of
  occasionally staying hidden.
• Favicon: app pages now declare the raster apple-touch-icon, so Firefox/Android use
  it for link previews and home-screen tiles instead of rasterizing the SVG.

Security

• Migrated JWT handling from the unmaintained python-jose to PyJWT.
