Maintainer handover

• With thanks to the CRAN team for looking after RJSONIO, Yaoxiang Li offered to help maintain the package after CRAN asked downstream package maintainers for a new maintainer.
• The handover followed the CRAN email thread from March 24 to April 5, 2025: CRAN asked for a new maintainer, Yaoxiang Li offered to help, CRAN accepted, and the package metadata was updated for the new release.
• This release records the maintainer transition and establishes a public GitHub source repository for ongoing CRAN maintenance.
