Add project status report and frontend documentation

- Introduced `PROJECT_STATUS.md` to provide a comprehensive overview of the MiroFish project, detailing the current status, completed features, and future development plans.
- Added multiple documentation files in the frontend directory, including detailed descriptions of the homepage functionality, startup guide, and project completion summary.
- Implemented a structured approach to document the project's architecture, API integration, and user interaction processes, enhancing clarity for developers and users alike.
- Included a `.gitignore` file to manage ignored files and directories in the frontend project, improving project organization and cleanliness.
