chore: remove legacy directories and update CI

Remove deprecated directories that have been superseded:
- infrastructure/ (replaced by infra/)
- apps/java21/ (replaced by apps/unicorn-store-spring/)
- apps/unicorn-store-javax/ (deprecated)
- apps/unicorn-store-jakarta/ (deprecated)
- apps/jvm-analysis-service/ (replaced by apps/ai-jvm-analyzer/)

Update CI workflow:
- Remove old build-java21 job (referenced deleted dirs)
- Add ai-jvm-analyzer build step to build-java25 job
- Remove jvm-analysis-service build step

Clean up dead legacy cleanup code in unicorn-store-spring setup script.

Previous state preserved in content-202605 branch.
