fix(host): compile punktfunk-host on windows (x86_64-pc-windows-msvc)

Browse Source 
Gate the Linux-only bits so the host crate builds on MSVC (it already built on Linux + macOS): drm_sync/dmabuf_fence use DRM ioctls + libc (a linux-only target dep) and have no non-Linux callers; VirtualOutput.remote_fd is a PipeWire concept. The full dep tree (aws-lc-rs, quinn, rusty_enet, axum) builds clean on MSVC and the binary runs (openapi emits the spec) — only these 3 cfg-gates were needed. First step of the Windows host port (docs/windows-host.md).
