 *
 * Runs are enumerated through the vendored Workflow World API and each
 * run's default stream is decoded through `Run.getReadable()` — the same
 * vendored read path the dev server uses to serve session streams over
 * HTTP — never by touching the store's private chunk encoding. The world
 * is opened for storage reads only: `start()` is never called, so queue
 * redelivery cannot be triggered by a CLI read, and unclosed streams
 * (crashed processes) are drained with an idle-timeout cancel instead of
 * waiting for chunks that will never arrive.
 *
 * Returns an empty list when the store does not exist. Selection is by
 * time window: events from any `eve dev` process in the window are
 * included, since the store does not attribute runs to processes.
