Non-Functional Delta: YU08-execution-algo-engine over YU07-historical-tick-store

Req	Status	Notes
NFR-AE01 independent of the BLP	Done	execution-algo-engine is a separate process/Deployment; no order-matcher Disruptor/journal/matching code is touched.
NFR-AE02 no new admission code path	Done	Children call the same POST /orders endpoint with the same request shape as the web front end's order ticket.
NFR-AE03 crash-resume with no operator step	Done	JetStream durable-consumer replay rebuilds every ParentOrder on boot; restart requires no manual intervention.
NFR-AE04 reuse existing client/framework	Done	io.nats:jnats:2.20.5 (already a project dependency via order-matcher/account-service), Spring Boot (same shape as every other JVM service).
