feat(cli_with_custom_uri): support environment base uri cli mode

Refactor shell command construction to use login shell (-l flag) on Unix-like systems,
ensuring that user environment variables are properly loaded from shell configuration
files (.bashrc, .profile, etc.) when executing the CLI through a pipe.

This change allows the CLI to access environment variables that may be required for
proper functionality, which is important when the command is invoked with stdin input.
