 * Pipeline engine that assembles and invokes the Dynamic Workflows runtime.
 *
 * Control flow (eligibility FIRST — avoids MissingKnobError on the downgrade path):
 *   1. if (!isWorkflowEligible(config))  → log once + return tsEngine.run(...)   ← NO args built
 *   2. cursor = reconstruct(...)         ← read-only (listContracts + loadHistory)
 *   3. args   = build(...)               ← pure; may throw MissingKnobError (acceptable: eligible)
 *   4. try { result = invoke(args); return flush(result) }
 *      catch WorkflowUnavailableError → log once + return tsEngine.run(...)  ← NO partial flush
 *      catch other → rethrow
 *
 * invoke() is DORMANT this release — always throws WorkflowUnavailableError.
 * The eligible path is only reachable in tests that force eligibility=true via
 * the injection seam (constructor param + vi.mock).
