Deckback v0.0.5

Fixed

• Settings menu no longer traps input after sleep/resume. If you opened the menu and the Deck
  slept (or the page reloaded for any reason), the menu could linger on screen while your controller
  drove the YouTube UI behind it — or the reverse, the menu could keep swallowing input with nothing
  on screen. The launcher now continuously reconciles "menu captured" with "menu actually painted",
  so a reload can never leave the two out of sync.

Changed

• Settings menu (OSD). The self-update pill/card are replaced by an in-app Settings menu:
  a persistent top-right button (active everywhere except during video playback) opens a
  controller-driven overlay with tabs. Settings ▸ Keys shows the controller hot-keys
  currently in use (read from your live config, never hardcoded). Updates shows whether you're
  up to date or has the changelog and actions for a new release. Open it with Menu (☰); navigate
  with the D-pad (and the right stick to scroll), A to select, B to go back/close, and
  L1/R1 to switch tabs. On the Updates tab, A on Update now installs (applies next launch)
  and Y ignores a version. An amber dot on the button flags an available update.
• Settings ▸ Keys now lists the L2 / R2 chapter-seek controls (Previous / Next chapter).
  They were being dropped because the launcher didn't recognise the chapter/skip seeks as controls
  it performs itself. The Updates tab's status and changelog text is also larger and better spaced.

Added

• About tab in the Settings menu: what Deckback is, its feature list, version, author, and
  project/support links — all read from the app's own store metadata (one source, so the in-app
  page can't drift from the Flathub listing).
