fix(macos/packaging): add NSLocalNetworkUsageDescription so Bonjour can register#5186

…an register Modern macOS denies Bonjour service registration with -65570 (kTCCServiceErr_PolicyDenied) when an app advertises NSBonjourServices but does not also declare NSLocalNetworkUsageDescription. The OS treats the missing key as opt-out and never prompts the user, so the Sunshine mDNS announcement silently fails and Moonlight cannot auto-discover the host. Adding the usage-description key lets macOS prompt for Local Network access on first launch and allow DNS-SD registration to succeed.

Description
src_assets/macos/build/Info.plist.indeclaresNSBonjourServiceswith_nvstream._tcpso the host can advertise itself for Moonlight auto-discovery, but it does not declareNSLocalNetworkUsageDescription. On macOS 14+ this combination causes mDNS service registration to fail with error-65570(kDNSServiceErr_PolicyDenied):Apple's Local Network privacy gate treats the missing usage-description key as an implicit opt-out: the OS never prompts the user for permission, and
DNSServiceRegisterreturnsPolicyDeniedsilently. The Bonjour record is never broadcast, so stock Moonlight clients can't auto-discover the server (users have to add the host by IP manually).Add a usage description so macOS prompts on first launch and allows the DNS-SD registration to succeed once the user grants Local Network access.
After this change, the startup log shows:
instead of the
-65570error, and Moonlight on iOS / Apple TV / macOS finds the host automatically over Bonjour.Screenshot
