docs: add comprehensive documentation for operations

This commit introduces a complete set of documentation files
covering various aspects of the project, including environment
setup, quality checks, command references, and architecture.
The documentation is structured to assist developers and
contributors in understanding the project's configuration,
workflow, and best practices.

Additionally, translations for Simplified and Traditional
Chinese have been added to ensure accessibility for a wider
audience. This enhances the overall usability and
maintainability of the project.
