jellytoast v0.1.1

This release is the working Linux .deb — the v0.1.0 package failed to
launch on modern Ubuntu — plus a cast-discovery fix and frosted/chrome support
for GNOME and other non-KDE desktops.

Fixed

• Linux .deb launches on modern Ubuntu (24.04 / 26.04). The bundle no
  longer ships libmpv's host-provided dependency closure, which on newer distros
  shadowed the system libraries and aborted startup with GLIBCXX_3.4.32 /
  MOUNT_2_40 errors (the app opened a "missing libmpv" dialog and quit with no
  audio). It now resolves those libraries from the distro's own libmpv. (#148)
• Linux .deb starts on X11 / XWayland sessions. Added libxcb-cursor0 to
  the package dependencies — Qt 6.5+ needs it to load the xcb platform plugin,
  and its absence aborted launch on X11 (Wayland was unaffected). (#149)
• Cast / AirPlay 2 discovery no longer deadlocks on Python 3.14. Cold imports
  of the optional discovery backends are serialized, sidestepping CPython 3.14's
  new import-deadlock detector. (#151)

Added

• Frosted glass + frameless chrome on GNOME and other non-KDE Wayland
  desktops. Where the compositor offers no app-controllable blur, the body now
  renders a faux frosted-glass texture instead of a flat panel (#152), and the
  window uses a frameless custom chrome (#153). KDE keeps its existing
  KWin-rule blur + decoration path unchanged.
