Remove 'log' command and related code

The 'log' subcommand and its CommandName variant were removed along with the module and handling in lib.rs because the project no longer supports or needs a separate 'but log' command. This cleans up the CLI enum, command dispatch, module imports, and help groupings to reflect that 'status' is now the sole inspection command.
