- Implemented ProjectService with methods for GetProject, CreateProject, UpdateProject, and DeleteProject.
- Implemented OrganizationService with methods for GetOrganization, CreateOrganization, UpdateOrganization, and DeleteOrganization.
- Defined corresponding request and response message types for each service.
- Generated gRPC code from proto definitions for seamless integration.
