Update all channel URLs from https://nixos.org/channels/ to https://channels.nixos.org/ to use the more reliable subdomain. The nixos.org domain apex lacks IPv6 support due to DNS hoster limitations. Using the subdomain allows better CDN distribution and improved reliability. Updated files: - Installation scripts (multi-user and tarball installers) - Channel URL resolution in eval-settings.cc - Documentation and examples - Docker image default channel URL - Release notes (added note about URL change) Fixes #14517
