fix(windows-drivers): driver Cargo.lock — pf-vdisplay gains windows + thiserror edges (STEP 5)

STEP 5 (b6486b3) added the windows + thiserror deps to pf-vdisplay/Cargo.toml but the
workspace lock was not updated (driver is windows-only, cant build on the Linux dev box).
Regenerated on the RTX box. Both crates were already resolved in the lock (pulled by
wdk-build), so this is purely the pf-vdisplay dependency edges.
