/**
 * Which harness the orchestrator runs on.
 *
 * The orchestrator's runtime is `runtimeType` in
 * `<crewlyHome>/teams/orchestrator/config.json` — the same field
 * `PUT /api/orchestrator/runtime` and StorageService.updateOrchestratorRuntimeType
 * write, and the one the orchestrator is launched with (a `DEFAULT_RUNTIME`
 * env var still overrides it at boot). Setting the orc harness also sets
 * `settings.general.defaultRuntime`, so new team members default to the one
 * harness first-time setup installed.
 *
 * This module writes the file directly (same lock key and atomic write as
 * StorageService) instead of instantiating StorageService, so the CLI can use
 * it without starting the backend's logger. `get` never creates the file:
 * a fresh machine reports null ("not chosen yet").
 *
 * @module services/harness/orc-harness.store
