/**
 * cleo-os Harness Registry.
 *
 * Layering (ADR-069 D002): the harness is the top of the Workflow layer.
 * Workflow MAY use Conduit (Messaging) for inter-agent DMs; Conduit MUST
 * NOT know about the harness (ADR-069 D002). Reverse imports from
 * `packages/core/src/conduit/` into `packages/cleo-os/` are forbidden.
 *
 * @see ADR-069 (CLEO Coordination Layers)
 *
 * Centralises construction and lookup of {@link HarnessAdapter} implementations
 * available in cleo-os. Adding a new harness means:
 *
 * 1. Implement {@link HarnessAdapter} in a subdirectory under `harnesses/`.
 * 2. Add an entry to {@link HARNESS_REGISTRY} below.
 * 3. Export the adapter class from the subdirectory's `index.ts`.
