feat(modules): harden module platform with event constants, validation checks, and CLI improvements

- Add ModuleEvents constants class with all 8 event strings; update dispatch call sites
- ValidateCommand: check AuthorizationPolicy container registration (check 20)
- ValidateCommand: warn on unknown event_listeners keys (check 21)
- make:module --simple flag for minimal manifests
- module:deactivate reverse-dependency warning
- 12 new PHPUnit tests covering all improvements
