Struct WindowCommandActionAvailabilityService 

pub struct WindowCommandActionAvailabilityService { /* private fields */ }

Window-scoped per-command “action availability” snapshots published by the UI layer.

This is a data-only integration seam used by cross-surface command gating (menus, command palette, shortcut help) without depending on fret-ui internals.

Semantics:

• None: no availability information is published for this window/command (treat as unknown).
• Some(true): command is available along the current dispatch path.
• Some(false): command is unavailable (blocked or not reachable) along the current dispatch path.
