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 legacy-patches/ (gitignored) - legacy-driver-guest/ (old guest vGPU driver, gitignored) - docs/old/ (superseded architecture write-up, gitignored) - docs that only reference the legacy components stay tracked; their path references now point at legacy-patches/ -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