openwms/org.openwms ? reverse-engineered prompt

Build me the root project for OpenWMS.org, a free and extensible warehouse management system for logistics and material flow control.

I want this repository to act as the main entry point for the platform, with clear project documentation and the shared core utility library that other OpenWMS services can use. Make sure the build works with the Maven wrapper and Java 25, and that the project is set up the way a real Spring based microservice ecosystem would expect. Include the shared exception types, utility helpers, and common event types that belong in the core library.

Also make the README feel useful for someone new to the project, with a short explanation of what OpenWMS is, how to build it, and how this root repo fits into the bigger system. If anything depends on current library or Spring Boot docs, look up the latest details online if you need to.
