feat(windows-drivers): STEP 8 (3/n) — re-vendor the installer driver from the new wdk-sys tree

The installer's vendored driver binary (packaging/windows/pf-vdisplay/) was STALE — built from the OLD
oracle tree (packaging/windows/vdisplay-driver/, wdf-umdf, SudoVDA-compat GUID), so it was
ABI-mismatched with the host (which opens the owned proto GUID 70667664). Re-vendor it from the NEW
drivers/ tree so the rewrite's ACTUAL driver is what the installer ships.

Built RELEASE on the RTX box from the new tree + the new .inx: cargo build --release -p pf-vdisplay ->
FORCE_INTEGRITY clear -> stampinf (DriverVer 06/25/2026,9.5.0625.1614, > the old 06/22) -> Inf2Cat
/os:10_X64 -> signtool sign the .cat with punktfunk-ds-test (.cat sig Valid). Replaces the stale
.dll/.inf/.cat; the .cer is unchanged (same cert).

ON-GLASS VALIDATED (install-test): pnputil /add-driver /install the release package -> clean WUDFHost
reload -> Status=OK, init_adapter -> IddCxAdapterInitAsync -> 0x0 (FP16 accepted),
IddCxMonitorCreate(id=1) -> 0x0. The shipping installer now installs + loads the real wdk-sys
proto-GUID driver, FP16/HDR-capable, monitor-create working.

Remaining STEP 8 (recorded in memory, deferred): re-point the stale "built from vdisplay-driver/"
comments in stage-pf-vdisplay.ps1 / pack-host-installer.ps1 / packaging README; selector default ->
pf-vdisplay unconditional; CI build-sign-or-stale-vendored drift guard; then DELETE the oracle tree.
KEEP sudovda.rs (runtime fallback + the backend-neutral CCD helpers pf_vdisplay.rs reuses) and the
WGC-relay/DDA secure path (the secure-desktop lock/UAC gate is not yet proven on glass for IDD-push).
