JRiver Remote 2.4.8

Highlights

• Official macOS and iOS / iPadOS builds. Tagged releases now publish
  JRiverRemote-macOS.zip (ad-hoc signed) and JRiverRemote-iOS.ipa
  (unsigned) on the GitHub Releases page, alongside the existing Android,
  Windows, and Linux artifacts.
• iOS Local Network permission. Adds the
  NSLocalNetworkUsageDescription Apple requires for any app on iOS 14+
  to talk to a server on the local network — without it the app would
  appear to launch but silently fail to reach Media Center.
• Build-from-source guide. A complete walkthrough in the README for
  installing prebuilt unsigned binaries (sideloading paths included) and
  for building from source with Xcode end-to-end.
• Refactored player core. Local and remote (MCWS) playback now share
  a single PlayerController interface, so every player command is one
  line in the unified provider instead of an if (zone.isLocal) ... else ... block. Lays the groundwork for adding new transports.
