Zuno: vanhemmat versiot ja versiohistoria

Accounts
- Switch between multiple YouTube Music accounts without signing out — add a second account and switch instantly. Settings → Account has full management (add, switch, remove); the title bar picker is a quick switch.
- Fixed: a stale macOS Keychain key could make a previously-signed-in session vanish after an update, showing as signed out even with a cached library still on screen.
Playback & Sound
- Pick your exact audio output device from Settings → Playback.
- Real output device list on Linux — actual speaker/headphone names via PipeWire/PulseAudio, with ALSA plugin/virtual noise filtered out.
- New equalizer bypass toggle, and a mini EQ right in the player bar.
- Fixed: some tracks would play 5-10 seconds then auto-skip.
- Fixed: crossfade could stall when the window was minimized.
- Fixed: a YouTube embed error (150/101) now falls back to native audio automatically instead of stalling playback.
- Fixed: a failed track preload could keep retrying the same broken URL instead of reloading fresh.
Playlists & Library
- Shuffle now truly shuffles the entire playlist, including songs already played — not just what's left in the queue.
- Loop button in the collection header cycles through all three states (off, loop all, loop one) instead of getting stuck on.
- Hide (and unhide) any playlist from your library.
- Start a radio station from any track's right-click menu.
- Fixed: shared/collaborative playlists now show up in "Add to playlist".
Interface
- Loading skeletons on Home, Album, Artist and Playlist pages instead of a blank flash.
- Larger, clearer Home section headings.
- Fixed: Home carousel cards could overflow the row horizontally.
- Fixed: hovering the mini player could drift it left over time.
- Fixed: switching tabs could show the wrong scroll position.
- Fixed: closing the last music tab while Settings/Library/History/Browse was open could break every playback control until restart.
Fixes
- Launching Zuno while it's already running now refocuses the existing window instead of opening a second one.
- "More recommendations" count now matches "Listen again".
- Zuno now prefers the official audio track over a music video release of the same song.
