CarDash 1.2.2 fixes the car volume on FYT/Syu head units and stops the volume card from jumping back to 100%.

The bug On FYT/Syu-based head units (Joying, Junsun, Teyes, Atoto and similar Chinese firmware) the amplifier belongs to the MCU. Android's media-stream volume is not what the driver hears, so setStreamVolume was accepted and ignored. The card then trusted the old read-back and snapped straight back to 100%, which made the car's real steps (10, 20, …) impossible to reach from the dashboard.

The fix

• CarDash binds the car's own com.syu.ms toolkit/sound module and sets the same master volume the car's OSD uses (0–36, MCU command C_VOL). It subscribes to the MCU level, so the dashboard and the car's knob now follow each other.
• If the car reports an old level after a write, the card keeps the requested value and marks it with ? instead of snapping back.
• Units without the Syu service keep the Android path, now with an extra FLAG_SHOW_UI write that can reach vendor volume panels.
• Volume diagnostics show the raw level/max, minimum, fixed flag, control source (syu, syu-wait, system) and vendor state. Long-press Media volume.
• No new permission, root or manifest change. The car's own knob and steering-wheel handling is untouched.

Also in 1.2.2

• Jellyfin Favorites tab, album-page heart and the playing-album Home shortcut.
• Jellyfin Streaming quality setting: Direct or 320/256/192/128 kbps MP3.

Verified

• 149 tests pass; flutter analyze clean; debug and release APKs build.
• The MCU volume path still needs the real-car test. After installing, long-press Media volume: source syu + vendor ready means the bridge is active. source system + vendor unavailable means this is not a Syu unit.
