Generate client-side protocol types from weft-shell-unstable-v1.xml
using wayland-scanner, following the same module structure as the
compositor server side.
- crates/weft-servo-shell/src/protocols/mod.rs: generate_interfaces!
inside __interfaces submodule, generate_client_code! at client module
level, with use wayland_client in scope. Re-exports
ZweftShellManagerV1 and ZweftShellWindowV1 for use by embed_servo
once the Wayland connection is established.
- New deps: wayland-client, wayland-backend, wayland-scanner, bitflags
(version-matched to existing workspace resolution).
The binding compiles but is not yet wired into embed_servo(); that
connection is deferred until the Servo embedder contract is ready.
