chore: Upgrade Reanimated to 4.4.0

[mrousavy]

Summary

• Upgrade react-native-reanimated from 4.3.0 to 4.4.0.
• Upgrade the paired react-native-worklets runtime from 0.8.1 to 0.9.1 because Reanimated 4.4.0 declares a react-native-worklets@0.9.x peer dependency.
• Refresh the example app Podfile.lock for RNReanimated 4.4.0 and RNWorklets 0.9.1.

Changelog review

• Reanimated 4.4.0 adds iOS Core Animation-backed CSS animation support behind IOS_CSS_CORE_ANIMATION, a feature-flagged animation backend, useTimestamp, Android precompiled headers, and several fixes.
• Worklets 0.9.1 adds cross-runtime promise support in Bundle Mode, shareable hosting outside the UI runtime, better scheduleOnRN errors, cross-runtime stack traces, and native logging improvements.
• I checked this repo for removed Reanimated exports (ColorSpace, InterpolateConfig, useInterpolateConfig) and deprecated Worklets serialization APIs; no code migration was needed.

Validation

• bun install --frozen-lockfile
• bun run build
• bun --cwd apps/simple-camera tsc --noEmit
• git diff --check
• PATH=/Users/mrousavy/.nvm/versions/node/v20.19.4/bin:$PATH /Users/mrousavy/.rbenv/versions/2.7.6/bin/bundle exec pod install

Notes

• Android assemble validation was attempted with ./gradlew :app:assembleDebug --no-daemon --stacktrace, but this shell cannot locate a Java runtime.
