v3.0.0-alpha.22 — React Native renderer ships

@pulse-music/react-native rc.1 — first real renderer

The 1-week RN sprint from REACT_NATIVE_RUNTIME_SETUP.md is collapsed into this alpha. Sentinel-throw stubs replaced with the real renderer powered by expo-av + react-native-reanimated.

What ships

• Audio playback via expo-av Audio.Sound
• 9 mood themes mirrored from @pulse-music/tokens
• Ambient EQ — 12 bars via Reanimated, off the UI thread
• Pulso heartbeat — concentric rings
• Inline player card + basic FAB + usePulseAudioRN hook
• PulseEngineRN class + singleton helpers
• Expo SDK 56 demo app at apps/demo-react-native/ — boots on Android emulator

Deliberately deferred (subsequent patches)

• Real FFT (waiting for react-native-audio-api iOS GA)
• Backdrop blur (expo-blur next patch)
• FAB drag-to-reposition (PanGestureHandler next patch)
• prefers-reduced-motion wiring

Intentionally absent

• Drag-to-resize, fullscreen API, guided demo tour (web-only concepts)

Quality gate

• 139/139 unit tests (was 132 in rc.0)
• @pulse-music/react-native: 10 sentinel tests → 17 real engine + parity tests
• Vue v2.3.4 byte-identical on its 23rd alpha

Publish status

@pulse-music/react-native carries version 3.0.0-rc.1 in code. The currently-published rc.0 (sentinels) gets superseded on the next npm publish --otp=XXXXXX run.
