The commit increases the version number from 0.9.1 to 0.9.2 in version.go. Additionally, an error check has been added in x25519.go to validate the private key size. Also, panel.go has been modified to accept both "NewV2board" and "V2board" as valid panel types.
Added a command line flag to allow the user to provide an input for the private key while utilizing the x25519 command. The function `x25519` was also modified to account for the possibility of a user-inputted private key. If no private key is provided, random bytes will be generated for the private key as before. This feature provides flexibility for the user in key management.
Reorganized the Go package structure, moving the main package to 'cmd'. Upgraded the flag library to Cobra for better management of CLI commands. This included moving the X25519 key generation from a flag to its own standalone Cobra command, which improves user interaction and code modularity. This structural change will benefit future additions and code maintainability.
