v1.0.0

First public release. The player was developed and used day to day on a real
Home Assistant install before being made generic and open-sourced.

Added

• Now-playing mini player docked at the bottom of the Home Assistant sidebar,
  just above Settings, on every page (not a dashboard card).
• Artwork, title, artist and speaker name; previous / play-pause / next;
  progress bar; volume slider and mute toggle (only when the player supports them).
• Zero-config auto-discovery of every media_player entity that is playing or
  paused, with optional include / exclude lists (* wildcards).
• Music Assistant de-duplication: a native player that mirrors an active Music
  Assistant player (same title or same name) is hidden.
• Several active players: a focused card plus slim collapsed cards above it,
  click to focus, hover to preview, "+N more" beyond a configurable cap.
• Collapsed (icons-only) sidebar: artwork with a play/pause overlay and a count badge.
• Optimistic play/pause: the button flips instantly and reverts after 8 s if
  the player never confirms.
• Paused players hide automatically after 5 minutes (configurable, or never).
• Swipe a card right to dismiss it until its state changes, with a dedicated
  touch path that works in the iOS companion app; a hover "x" for mouse users.
  Dismissals are remembered per browser (localStorage).
• Video apps without track metadata (for example Netflix on Apple TV) show the
  app name and a TV placeholder icon.
• Optional configuration via window.sidebarMiniPlayerConfig: include,
  exclude, paused_timeout_minutes, position (bottom / top),
  accent_color, max_collapsed_cards, max_collapsed_cards_short_window,
  dedupe_music_assistant, swipe_to_dismiss, show_dismiss_button,
  show_volume, show_progress, remember_dismissed. Changes apply live.
• Theme support through Home Assistant CSS variables, plus
  --sidebar-mini-player-accent-color, --sidebar-mini-player-card-background
  and --sidebar-mini-player-border-radius.
• Works when loaded with frontend: extra_module_url (every page) or as a
  dashboard resource; loading it twice is harmless.
• HACS packaging, jsdom test suite (npm test) and GitHub Actions for HACS
  validation, tests and releases.
