Summary

• Deploy fails because feign-apt-test-generator has a test-scoped dependency on feign-example-github, which is excluded from the reactor during deploy. Maven still resolves test dependencies even with -DskipTests=true, so the SNAPSHOT jar can't be found.
• Internalizes the test fixtures by copying GitHubExample.java and moving GitHubStub.java into src/test/resources/ (used as APT input and golden file, not compiled by Maven)
• Replaces the feign-example-github dependency with feign-core + feign-gson (published modules that are always resolvable)

Test plan

• mvn clean test -pl apt-test-generator -am passes
• mvn dependency:resolve -pl apt-test-generator resolves without feign-example-github
• Full reactor build passes (excluding pre-existing jaxrs3/jaxrs4 failures)
