This adds foundational functionality for nixos-facter hardware detection: - lib.nix: Internal helper functions for querying facter reports - hasCpu/hasAmdCpu/hasIntelCpu: CPU vendor detection - collectDrivers: Extract driver_modules from hardware entries - toZeroPaddedHex: Format USB device IDs (for fingerprint matching) - system.nix: Auto-detect nixpkgs.hostPlatform from facter report Automatically sets the correct platform (x86_64-linux, aarch64-linux, etc.) based on the hardware report, reducing manual configuration. This builds on the base infrastructure added in PR #450303 and provides the foundation for upcoming hardware detection modules (boot, networking, graphics, etc.).
