Subject: Split crates/wayland/src/state.rs (1276 lines) into state/

Pure reorganization, no behavior change - verified by diffing the
function-name and struct-name sets before/after (both identical) plus
a full cargo test pass. mod.rs keeps ClientState/OutputEntry/CompState/
WindowAnim/RepeatState's definitions, the key-repeat impl, and the
output-lookup impl (all small and tightly coupled to the type
definitions), plus mod declarations. The one large impl CompState
block (previously ~600 lines) splits by concern:

- lifecycle.rs: new_managed_window, set_decorated_from_mode,
  redraw_decoration_buffer, remove_window.
- layers.rs: ensure_layer_initial_configure.
- focus.rs: set_keyboard_focus, set_window_activated.
- menu.rs: open/close/run_context_menu_action, is_double_click.
- geometry.rs: raise_pinned, sync_geometry.
- tick.rs: tick_dirty_broadcasts, tick_animations,
  resync_stacking_order.
- toplevel.rs: the with_toplevel_title/app_id/sync_toplevel_metadata
  free functions.
- tests.rs: unsplit, same reasoning as every other split this pass.

CompState's fields were already pub(crate) (this crate's existing
convention, unlike core's/config's plain-private), so no field-
visibility changes were needed - only resync_stacking_order (called
from geometry.rs, defined in tick.rs) needed bumping from private to
pub(crate), matching that same convention.
