/**
 * `arts/buss` — engine implementation of the event bus.
 *
 * Only the runtime factory lives here. Interfaces, generic constants,
 * error classes, the `SILENT_BUS` no-op, and pure helpers live in
 * `$libs/bus`.
 *
 * Modules that need to publish or subscribe MUST import their types
 * from `$libs/bus`. They MUST NOT import from `$bus` — that is
 * reserved for the composition root (`aapp`) and tests that need the
 * concrete engine.
