Bernardo Magri c57d26864e feat(hardware): nomarchy.hardware.* enablement beyond nixos-hardware
The nixos-hardware "common-*" profiles the installer selects cover the
basics (microcode, the Intel/AMD VA-API media stack, weekly fstrim), and
power.nix adds thermald + power-profiles-daemon. This adds the gap above
them, generically and detected at install time.

New modules/nixos/hardware.nix exposes a vendor-keyed nomarchy.hardware.*
surface — broadly-beneficial bits default ON when the vendor is detected
(opt-out), heavy/experimental bits behind opt-in toggles:
  - intel.enable -> GuC/HuC (i915.enable_guc=3); intel.computeRuntime
    (opt-in: intel-compute-runtime + vpl-gpu-rt)
  - amd.enable -> amd_pstate=active + radeonsi VA-API env; amd.rocm.enable
    + amd.rocm.gfxOverride (opt-in: ROCm HIP/OpenCL)
  - fingerprint.enable -> fprintd; fingerprint.pam (opt-in: login + sudo)
  - npu.enable (opt-in/experimental) -> the in-kernel driver
    (amdxdna/intel_vpu) keyed by vendor; userspace runtime is BYO

hardware-db.sh now detects Intel/AMD, a fingerprint reader (libfprint USB
vendor IDs) and an NPU (Intel VPU / AMD XDNA PCI IDs), emitting NOMARCHY
lines the installer bakes into system.nix — safe defaults active, opt-ins
commented. Audited against the commons to avoid double-setting.

Verified: flake check green; a toggles-on build has amd_pstate=active +
i915.enable_guc=3 in kernel-params and ships fprintd.service; detection
runs correctly on the (AMD Ryzen-AI) dev machine. On-hardware verification
of the AMD/NPU/Intel-compute runtime bits is still pending.

Docs: template commented examples, README option table, ROADMAP status.
