Add support for text output

We'd like to support a text output, it should be the default and if --output=json is passed, we'd toggle to JSON.

The responses should be:

• Create Store: Store <ID> successfully created.
• List Stores:

id, name, created_at, updated_at
<store_id>, <store_name>, <created_at>, <updated_at>

• Get Store:

id : <store_id>,
name: <store_name>,
created_at: <created_at>,
updated_at: <updated_at>,
deleted_at: <deleted_at>

• Delete Store: Store <ID> successfully deleted.

• List Models:

// Model ID : <ID>, // Model : <JSON>

• Write Model

Model <ID> successfully created.
Model: <JSON>

• Get Model

<JSON>

• Write: Tuple successfully added
• Delete: Tuple successfully deleted
• Read:

user, relation, object, date created
<user>, <relation>, <object>, <timestamp>

• Read Changes:

Tuple <tuple in tuple format> ADDED at <timestamp>.

• Check: Allowed : True | False
• List Objects:

<object_type>:<object_id>
<object_type>:<object_id>
<object_type>:<object_id>
<object_type>:<object_id>

• List Relations:

relation1
relation2

Start at the CLI entry points for the Store, Model, tuple, Check, List Objects, and List Relations commands, then trace how the existing JSON output is selected. Run each command to compare current behavior with the requested text responses and verify that text is the default while --output=json preserves JSON output. Done means all listed commands emit the specified text format.
