 * In-process event adapter that delivers events via registered callbacks.
 *
 * Plugs into the existing `eventRegistry` alongside Socket.IO / NATS.
 * SDK callers subscribe with `.on()` and receive events as direct
 * function calls — no network transport, no serialization overhead.
 *
 * Supports NATS-style pattern matching:
 * - Exact: `on('task.created', cb)`
 * - Single-token wildcard: `on('task.*', cb)` — matches task.created, task.failed, etc.
 * - Multi-token wildcard: `on('app.epic.>', cb)` — matches app.epic.apis.createorder.error
 * - Global wildcard: `on('*', cb)` — matches every event
