Java SDK for flowd (github.com/krishnakichuu/flowd). A standalone,
multi-module Maven project — a sibling of flowd-engine (the Go server),
not nested inside it and not part of its build graph.
Module layout:
flowd-sdk-core framework-agnostic core: annotations,
replay engine, client, worker. The only
module every application depends on.
flowd-sdk-spring-boot-starter optional ...
