chore: update submodule references and documentation

- Marked submodules ai-mcp-pmm-controller, explorer-monorepo, and smom-dbis-138 as dirty to reflect recent changes.
- Updated documentation to clarify operator script usage, including dotenv loading and task execution instructions.
- Enhanced the README and various index files to provide clearer navigation and task completion guidance.
