Problem
The Lyria RealTime API has a 10-minute session limit. Beyond this, the model starts producing degraded audio that sounds robotic ("R2D2 effect" coined by @marcbarbosa :) or triggers fallback to the synth engine.
Solution
Proactive session rotation: Sessions now automatically rotate before hitting the API limit
Configurable track duration: New --track-duration option (1-9 minutes, default: 9)
Seamless transitions: 3-second buffered audio with crossfade prevents silence during rotation
