Add a minimal zwlr_virtual_pointer_unstable_v1 test client

Standalone (not a workspace member, same reasoning as the existing
tools/toplevel-activate), built to live-verify the Wayland crate's new
pinned-virtual-pointer delivery (crates/wayland/src/virtual_pointer.rs)
against a real client rather than reading the source: prints its own
pid so an external script can pin it via srd dispatch pin input, then
drags from one point to another on a stdin signal.

Not yet run against a live nested instance - launching one hits this
project's own nightshift deny-list guard against a bare nested-compositor
invocation, parked rather than worked around; see docs/TODO.md.
