Use .get() and .set() for Shared Values with React Compiler

With React Compiler enabled, use .get() and .set() instead of reading or writing .value directly on Reanimated shared values. The compiler can't track property access—explicit methods ensure correct behavior.

Incorrect (breaks with React Compiler):

import { useSharedValue } from 'react-native-reanimated'

function Counter() {
  const count = useSharedValue(0)

  const increment = () => {
    count.value = count.value + 1 // opts out of react compiler
  }

  return <Button onPress={increment} title={`Count: ${count.value}`} />
}

Correct (React Compiler compatible):

import { useSharedValue } from 'react-native-reanimated'

function Counter() {
  const count = useSharedValue(0)

  const increment = () => {
    count.set(count.get() + 1)
  }

  return <Button onPress={increment} title={`Count: ${count.get()}`} />
}
