* Add go.mod files for cache, eventbus, and scheduler modules

- Created independent go.mod files for modules/cache, modules/eventbus, and modules/scheduler
- Ran go mod tidy on all modules to resolve dependencies
- Applied go fmt formatting to all module files
- All tests are now passing for individual modules
- Fixed module structure to work as independent packages

* Tests passing, readmes updated.
