refactor: rename pf-vdisplay-proto -> pf-driver-proto (it spans all drivers)
The shared host<->driver ABI crate already contains more than the virtual display: the IDD-push frame ring + control plane AND the gamepad shared-memory layouts (XusbShm / PadShm). "pf-vdisplay-proto" was a misnomer — the name now represents all the drivers it serves. Mechanical rename, no behavior change: - git mv crates/pf-vdisplay-proto -> crates/pf-driver-proto (package name + path-deps in the host crate and the driver workspace). - pf_vdisplay_proto -> pf_driver_proto across host + driver Rust, both Cargo.lock files, the workspace members, the CI path triggers (windows-drivers.yml), and the docs/INF comments. The runtime Global\pfvd-* shared-object names are a SEPARATE contract and are deliberately untouched (host<->driver name matching). - The pf-vdisplay DRIVER crate + its INF service name (Root\pf_vdisplay, UmdfService=pf_vdisplay, pf_vdisplay.dll) are unchanged — only the full `pf_vdisplay_proto` token was replaced, never the `pf_vdisplay` driver name. Linux-verified: cargo test -p pf-driver-proto (const size-asserts compile) + cargo clippy -p punktfunk-host -D warnings clean; Cargo.lock regenerated. The driver-workspace side (path-dep + imports + its Cargo.lock) is Windows-CI-gated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
