enricobuehlerandClaude Fable 5 786f6ad28f fix(pf-driver-proto): catch the layout tests up with the cursor-channel proto bump

The cursor-channel sweep grew AddReply by the cursor_excluded u32 tail (24
bytes, legacy prefix 20) and bumped PROTOCOL_VERSION to 6, but left two lib
tests behind: the AddReply byte-layout roundtrip still built the legacy
initializer (a compile error that turned the rust CI leg red on main), and
the version-coherence assertion still pinned v5 (hidden behind that compile
error). Cover the new tail bytes + the legacy-size constant, and widen the
compat-window note to v4–v6 (floor stays 3).

pf-driver-proto

The shared host ↔ driver binary contract for punktfunk's Windows pf-vdisplay virtual display — the control IOCTLs and the IDD-push frame transport, defined exactly once.

It's a path dependency of both the host workspace (crates/punktfunk-host) and the out-of-workspace driver workspace (packaging/windows/drivers/), so it must resolve identically from either build graph. That's why it's deliberately self-contained: no_std (+ alloc), platform-neutral (GUID/LUID are plain integers each side converts to its own OS type), and free of *.workspace = true inheritance.

Defining every wire struct here — with const size/offset asserts and bytemuck round-trips — turns host↔driver ABI drift into a compile error instead of a silent frame or IOCTL corruption.

See the crate root (src/) for the wire types; the Windows virtual-display design is in the internal planning repo (punktfunk-planning: windows-virtual-display-rust-port.md).
