Feature/axoniq/137/demo message transformation

[laura-devriendt-lemon]

Add university-message-transformation demo module

Sits alongside university-demo in examples/. Demonstrates the AxonIQ Framework 5.2 event message transformation chain end to end. See the module README.md for setup, layout, and how to run.

Spec coverage

All MUST-tier 5.2.0 FRs from the plan in https://github.com/AxonIQ/axoniq-framework/pull/153 are covered

Focused FR verification

Each FR should be backed by a named test the reviewer can run individually => for example

mvn test -Dtest=ChainLockingTest          # FR-004
mvn test -Dtest=ChainConcurrencyTest      # FR-006
mvn test -Dtest=MetadataPreservationTest  # FR-010
mvn test -Dtest=OutputIdentityCheckTest   # FR-018
mvn test -Dtest=DecorationOrderTest       # FR-021
mvn test -Dtest=HistoricEventsUpcastingIntegrationTest  # end-to-end

You can also choose to play around with the live shell and replaying by using AxonIQ Platform

Notes

• Tests run in-memory by default; the README explains how to flip to Axon Server.
• AxonIQ Platform reporting stays dormant unless .env is populated.
• check if Pom dependencies are okay please
