Enum CommandAvailability 

pub enum CommandAvailability {
    NotHandled,
    Available,
    Blocked,
}

Command availability query result used by UiTree::is_command_available (ADR 0218).

This is a pure query signal (no side effects). Consumers typically interpret:

• Available: command should be treated as enabled for the current dispatch path.
• Blocked: command must not bubble further to ancestors for availability purposes.
• NotHandled: this node does not participate in availability for this command.
