Fix cache warmer: add clean + resolve all declared plugins

maven-clean-plugin:3.2.0 and exec-maven-plugin:1.2.1 were missing from
cache because:
- warmer ran without 'clean' lifecycle (missed maven-clean-plugin)
- exec-maven-plugin has no lifecycle binding (only declared, not bound)

Fix: add 'clean' to all steps AND add dependency:resolve-plugins step
to resolve ALL declared plugins including those without executions.
