Add 'manifest' package and integrate it with 'command_init'

A new package named 'manifest' is introduced in this commit. It comprises a single structure and related functions for managing manifests. Additionally, 'command_init' has been altered to use this new module instead of using its previously hard-coded functionality. A reference to 'manifest' has also been added in the Cargo.lock and command_init/Cargo.toml files.
