// Shirabe's own definition of Composer\EventDispatcher\Event for the plugin worker. This class
// lives in both worlds at once: an instance revived from a Rust handle proxies every call over
// RPC (like a generated stub), while an instance constructed natively — real Composer code in
// this process does `new PreCommandRunEvent(...)`, whose parent constructor lands here — is a
// faithful in-process port of the real base class. Proxy revival binds the handle without
// running the constructor, so the constructor below is the native mode alone;
// `__shirabeRustHandleDescriptor()` returns null there so the wire codec registers the object in
// the P table instead of treating it as a Rust handle.
