Type Alias TemplateHook 

pub type TemplateHook = Arc<dyn Fn(&TemplateEvent) + Send + Sync + 'static>;

Type alias for template event hooks.

Hooks are functions that receive a reference to a TemplateEvent and can perform any side effects (logging, metrics, etc.).

Hooks must be:

• Send + Sync for thread safety
• 'static lifetime to be stored in the parser
