/**
 * @file
 *
 * Pure helpers for parsing `adb devices` output.
 *
 * Kept separate from the integration-only `transport-factory` (excluded from
 * unit tests) so the parsing stays unit-testable — the factory itself shells out
 * to `adb`.
 *
 * The listing answers two **different** questions, and conflating them is a
 * defect rather than a nicety:
 *
 * - *Is the device usable?* — only a device in the `device` state is, which is
 *   what the session preflight asks ({@link listOnlineDeviceIds}).
 * - *Is the device gone?* — a dying emulator drops to `offline` while it still
 *   holds the AVD's `multiinstance.lock` and its console port, so teardown must
 *   treat **any** listed state as "still here" ({@link checkIsDeviceListed}).
 *   Reading `offline` as gone is what lets the next run collide with a leftover.
