feat(hw): #58 nomarchy-detect-hw post-install re-probe CLI

Package the installer’s pure hardware-db probe as nomarchy-detect-hw:
prints suggested hardwareProfile and system.nix snippets (or --raw
protocol lines). Does not rewrite the flake. On PATH via the distro
module; docs/HARDWARE.md §8 updated. Close #58.

Verified: V1 (build + run on AMD laptop with fingerprint/NPU/IR cam).
