The Event system provides a minimal, type-safe, and cache-friendly mechanism for communication between engine subsystems. Events are simple data structs tagged with an EventType and EventCategory bitmask for quick categorization and filtering.

Dispatching is done via a templated function that matches types using compile-time StaticType() identifiers, eliminating the need for virtual dispatch.
