/**
 * Resolution of the `ownership` posture options (`Engine.create({ ownership })`)
 * into {@link ResolvedOptions}. Extracted from `construction.ts` to keep that
 * file under the `max-lines` ceiling; mirrors the second-instance resolver's
 * "only validate when the feature is enabled" discipline.
 *
 * `ownership` is a three-member discriminated union — `'none'`, `'lease'`
 * (a single store-wide lease), and `'workflow-lease'` (per-workflow fencing,
 * ADR 0002 at
 * `documentation/contributing/architecture-decisions/0002-multiengine-per-workflow-ownership.md`).
 * This module resolves and validates the option surface only: it resolves the
 * `workflowClaimTtl`/`workflowClaimRenewInterval` tuning fields and rejects
 * incoherent configuration. The fencing behavior itself lives in the claim
 * registry, the ownership bootstrap, and the fenced-write path.
 *
 * @module core/engine/ownership-options
