fix: address review feedback on finalKey merge block

- Guard finalKey block with config.target.length === 1 so it only runs
  for length-1 array targets, not nested paths handled by recursion
- Explicitly write filtered rightValue in all code paths to prevent
  unfiltered VAR_SYMBOL objects from leaking into RN props
- Add defensive comment about leaf-key storage limitation in getStyledProps
