Add nvidia-optimus plugin

nvidia-optimus

Monitor and control an NVIDIA Optimus dGPU on Hyprland from the bar. A theme-tinted NVIDIA "eye" shows the dGPU's power state (accent = awake, neutral = asleep); clicking it opens a panel with a Battery ⇄ HDMI-Ready toggle, live power/temp/VRAM, and the list of processes holding the GPU (compute + graphics, including container/root procs that lsof can't see).

Why: on Hyprland an NVIDIA Optimus dGPU often won't RTD3-suspend even when idle — the compositor's EGL keeps it pinned — quietly draining battery. Meanwhile the HDMI port is frequently wired to the dGPU, so you can't just disable it. This plugin switches between "let the dGPU sleep" (drop it from AQ_DRM_DEVICES + force mesa-only EGL) and "HDMI-Ready", and surfaces the true power state at a glance.

Notes for review:

• Ships three small bash helpers under scripts/ (run via bash, no exec bit required). They read sysfs / nvidia-smi and edit the user's ~/.config/hypr/env.conf (backed up on every change). Both GPUs are auto-detected from sysfs — nothing machine-specific is hardcoded.
• The background poll is sysfs-only and never wakes the dGPU (name resolved from pci.ids, connectors on a sleeping dGPU are not probed). nvidia-smi runs only while the panel is open, and only when the GPU is already awake.
• Hyprland-specific (uses AQ_DRM_DEVICES); requires the proprietary NVIDIA driver + nvidia-drm.modeset=1.
• Precedent for hardware/script plugins in the registry: asus-um5606-fan-state, battery-and-power-management, arch-updater.
