10.3.0-canary-20260305205402

Summary

• add POST /select-story-sync/:storyId to the React Native channel server and extract the implementation into selectStorySyncEndpoint.ts
• wait for a matching storyRendered event before returning success, with a 500ms fast-path for already-rendered stories and a 1000ms timeout otherwise
• track rendered state per connected socket so disconnected clients cannot cause false-positive sync responses
• add channel server integration tests covering success, already-rendered, timeout, and disconnect/reconnect cases
• switch the Expo Maestro screenshot flows from repeated deep links to channel-server-driven story selection via select-story-sync
• add generated Maestro capture/assert flows and move the checked-in screenshot baselines under .maestro/output/screenshots
• update buildIndex to respect explicit story.id values so generated Maestro story IDs match the actual story index
• document the new endpoint in the example channel server script output and scope LogBox suppression to screenshot runs only
• refresh the Storybook alpha dependency set used by the example and workspace packages

Testing

• pnpm --filter @storybook/react-native test -- channelServer.test.ts
• pnpm --filter expo-example check
