Refactor and rebrand Rojo to Atlas

- Renamed the project from Rojo to Atlas, updating all relevant files, scripts, and documentation to reflect the new branding.
- Bumped version to 7.7.0-rc.2 and updated protocol version from 5 to 6.
- Modified installation scripts and CI workflows to use the new binary name and paths.
- Adjusted plugin settings and internal identifiers to prevent conflicts with the original Rojo.
- Enhanced session management and API response handling to support the new server fork identifier.
- Updated project templates and README files to guide users on using Atlas.
