Module bus 

EventBus: serial event dispatcher feeding Lua handlers registered via bus.on(kind, fn) / bus.on_any(fn).

This subtask (Subtask 1) defines the pure-Rust core: Event, Source, EventBus, plus a Handler trait placeholder that Subtask 3 will swap for an mlua::RegistryKey-backed implementation.

Module wiring (mod bus; in main.rs) and tokio-util Cargo dependency are deferred to Subtask 2.
