Move platform-specific network interface detection from cmd/cli/ to root package as ValidInterfaces function. This eliminates code duplication and provides a consistent interface for determining valid physical network interfaces across all platforms. - Remove duplicate validInterfacesMap functions from platform-specific files - Add context parameter to virtualInterfaces for proper logging - Update all callers to use ctrld.ValidInterfaces instead of local functions - Improve error handling in virtual interface detection on Linux
