Hardware runner

Installs the selected source-neutral hardware baseline. Modes are preflight and apply.

Inspect available host policy

wget -qO- https://devs-guide.github.io/debian/setup/hardware.sh | \
  env DEBIAN_HARDWARE_MODE=preflight bash

Apply an explicit host baseline

wget -qO- https://devs-guide.github.io/debian/setup/hardware.sh | \
  env DEBIAN_HARDWARE_MODE=apply \
      DEBIAN_HARDWARE_ARCHIVE_TOOLS=1 \
      DEBIAN_HARDWARE_FIRMWARE=1 \
      DEBIAN_HARDWARE_DEV_TOOLS=1 \
      DEBIAN_HARDWARE_APPLY_PERFORMANCE=0 \
      DEBIAN_HARDWARE_CPUPOWER_ENABLE=0 \
      DEBIAN_HARDWARE_USB_AUTOSUSPEND_DISABLE=0 \
      DEBIAN_HARDWARE_DISABLE_CONSOLE_BLANKING=0 \
      DEBIAN_HARDWARE_POWER_POLICY=0 \
      bash

Variable	Purpose
`DEBIAN_HARDWARE_MODE`	Selects read-only `preflight` or mutating `apply`.
`DEBIAN_HARDWARE_ARCHIVE_TOOLS` / `DEBIAN_HARDWARE_DEV_TOOLS`	Opts into the reviewed archive and development-tool package groups.
`DEBIAN_HARDWARE_FIRMWARE`	Opts into the firmware package group. Confirm the hardware/licensing policy first.
`DEBIAN_HARDWARE_APPLY_PERFORMANCE`	Enables the performance playbook only when explicitly set to `1`.
`DEBIAN_HARDWARE_CPUPOWER_ENABLE`, `DEBIAN_HARDWARE_USB_AUTOSUSPEND_DISABLE`, `DEBIAN_HARDWARE_DISABLE_CONSOLE_BLANKING`, `DEBIAN_HARDWARE_POWER_POLICY`	Individual power/console policy toggles. They remain `0` above for a conservative baseline.

GPU vendor packages and GPU policy are deliberately outside this runner. Use the NVIDIA runner when an NVIDIA/CUDA configuration is required.
