v1.1.2 - Spatial Audio & UI Improvements

Changes in 1.1.2

• 4-Channel 8D Spatial Audio System:
  • Introduced discrete speaker role assignment (Front, Back, Left, Right) using StrictChannelMatrix and SpatialDspEngine.
  • Built low-latency UDP media transport with LeaderDomainClock presentation PTS timestamps.
  • Added interactive Devices Stage management UI and top-down 3D soundstage preview canvas.
  • Added Host-local dual-mono loopback rendering and atomic session teardown policies.
• High-Precision Acoustic Sync Trim:
  • Upgraded trim resolution to 0.125 ms increments with quick nudge buttons (-0.125ms / +0.125ms / Reset) and 3-decimal readout precision.
  • Made the trim card layout responsive with dynamic typography and compact button padding for small screens.
• Join Screen Clean-Up:
  • Removed the Devices tab from the Join Screen bottom navigation bar to keep channel setup exclusively on the Host.
• Network & Lifecycle Hardening:
  • Added per-packet error isolation in the TCP read loop to prevent socket drops on handler exceptions.
  • Fixed Android foreground service start-in-time race conditions during rapid playback stop/start cycles.
