/**
 * Mock `IProsePipeline` implementation for engine tests — sub-phase 1.5.
 *
 * Mirrors the behavior of the legacy `MockTextService` so existing
 * tests can swap to this without surprise. In sub-phase 1.6 the
 * legacy `mock-text-service.ts` is deleted and engine test code
 * imports from this module instead.
 *
 * Public interface: `MockProsePipeline`, `createMockProsePipeline`.
 *
 * Owner context: `@sharpee/engine` — test helpers.
 *
 * @see ADR-174 §Internal interfaces
