Untrack legacy trees and purely legacy docs (kept locally)

- patches/ -> legacy-patches/ (gitignored)
- legacy-driver-guest/ (old guest vGPU driver, gitignored)
- docs/old/ (superseded architecture write-up, gitignored)
- docs that only reference the legacy components stay tracked; their path
  references now point at legacy-patches/
- install.sh PATCH_DIR updated

-# NVIDIA open-gpu-kernel-modules Patches
-
-Open-IOV does **not** vendor the NVIDIA OpenRM source tree. Instead, the
-installer clones upstream at a pinned tag and applies this patch series.
-
-## Pinned upstream
-
-- Repository: <https://github.com/NVIDIA/open-gpu-kernel-modules.git>
-- Tag: `610.57.04`
-- Pristine-tree SHA256 of the delta base: tag `610.57.04`
-
-## Applying
-
-```bash
-git clone --depth 1 --branch 610.57.04 \
-    https://github.com/NVIDIA/open-gpu-kernel-modules.git
-cd open-gpu-kernel-modules
-git apply /path/to/open-iov/patches/nvidia/*.patch
-```
-
-(`install.sh` does this automatically.)
-
-## Regenerating the series
-
-If you modify the NVIDIA tree, regenerate the patches with:
-
-```bash
-cd nvidia-open-gpu-kernel-modules
-git format-patch 610.57.04..HEAD -o ../patches/nvidia/
-```
-
-## What the series does
-
-`0001-Build-fixes-and-vGPU-VFIO-interface-integration.patch`:
-
-- Adds the vGPU VFIO interface headers (`nv-vgpu-vfio-interface.h`,
-  `nv-vgpu-vfio-interface-nvidia.h`) that `open-iov-vfio.ko` and
-  `nvidia.ko` share.
-- Exports the vGPU VFIO symbols from `nvidia.ko`
-  (`nvidia_vgpu_vfio_probe/remove`, `nvidia_vgpu_vfio_get_ops/set_ops`,
-  `nv_vgpu_mdev_register_parent/unregister_parent`, ...).
-- Reports version `570.144` to match the GSP firmware the guest driver
-  stack is validated against.
-- Build fixes for kernel 6.8 out-of-tree builds and the
-  `Module.symvers.open-iov` reference list.
