Type Alias SharedHookRegistry 

pub type SharedHookRegistry = Arc<RwLock<HookRegistry>>;

Thread-safe shared reference to a HookRegistry.

Follows the same pattern as SharedChannelHandles in the runtime:

• dispatch() takes &self → read lock
• register() / unregister() take &mut self → write lock

std::sync::RwLock (not tokio) because the lock is never held across .await points.

Aliased Type

pub struct SharedHookRegistry { /* private fields */ }
