Fix decoration drift during animated transitions; checkpoint IPC/global-menu/output-management work

Border/titlebar decoration was built from Window.geometry (the animation's
final target) in both wayland backends' render loops, while sync_geometry
already draws a window's actual content at window_anims' interpolated rect
during any maximize/fullscreen/open-slide tween. Border and content read two
different rectangles for the whole transition, so the border visibly
detached from the window it was outlining - reported as "borders aren't
flush." Both udev.rs and winit.rs now read the same animated rect for
titlebar placement, border-strip placement, and the occlusion test against
later windows in stacking order. Verified: cargo build --workspace, cargo
clippy (0 new warnings), cargo test -p srdwm-core (111/111).

Also checkpoints substantial protocol/IPC work from prior sessions that had
accumulated uncommitted: gtk-shell1 support (gtk_shell.rs, the vendored
gtk-shell.xml, xwayland.rs's X11-side mirror) backing the global app menu;
zwlr_foreign_toplevel_manager_v1 (foreign_toplevel.rs) broadcasting distinct
maximized/minimized/fullscreen/activated state per window; output_management
(ext-output-management + layer-shell exclusive-zone reservation tracking);
workspace.rs and context_menu.rs; a Unix-socket IPC crate (platform/src/
ipc.rs) and a `srd` control-CLI crate (crates/ctl); xkb_config.rs; and a
theme module (core/src/theme.rs). A peer session working the AGS shell
concurrently verified several of these live against a running srdwm: the
global menu rendering a real app's File/Edit menu over gtk-shell1, and
foreign-toplevel correctly reporting maximized and fullscreen as independent,
non-simultaneous states with the geometry each implies (maximize stops at a
reserved top bar and past a dock; fullscreen reaches the true monitor edge).
