Phase B core (plan §5/§8): - engine/Mixer.h: lock-free slot state machine (Free→Active→Draining→Free), channel #0 = the RendererBus byte-compatible permanent default, lazy ~512KB ring allocation per claimed slot (high-water, never freed under a live audio thread), per-channel gain/mute with block ramps (click-free), fade-to-silence reclaim (§5), hard cap 24 with no-capacity refusal (§8.9), group start gates at block granularity (§8.13), native gain clamp via sanitizeStreamGain (§5.1 tier 2). - AudioEngine: mixer replaces the bare rendererBus member; setRendererBus/pushRendererAudio/getRendererBusMetrics delegate to channel #0 unchanged; pullRendererBus now mixes all ready channels (duplex + split paths and the StreamSink submix carry every channel). - N-API: mixerCreateChannel/Release/Push/SetGain/SetMute/SetGroup/List. - tests/engine_units/mixer_test.cpp: byte-compat vs plain RendererBus, cap refusal, live-consumer fade-then-free, ramp clamps, group gate, bounded strings. renderer_bus_test still green.
