Covers the full design for runtime codec switching based on network
conditions: 3-tier basic (GOOD/DEGRADED/CATASTROPHIC), extended
5-tier with studio levels, and bandwidth probing. Details the
existing QualityAdapter infrastructure, what's missing (report
ingestion, profile switch loop, cross-task signaling via AtomicU8),
and implementation plan for both Android and desktop engines.
