fix: only run tests for affected modules, not dependencies

Split the build into two phases:
1. Build dependencies without tests using -am -DskipTests
2. Run tests only for affected modules and their dependents

This prevents running tests for upstream dependencies like
spring-ai-commons and spring-ai-model when they're not in
the affected module list.
