ark-cli: CI Tests

[tareknaser]

Description:

ark-cli crate currently lacks CI workflows.

Motivation:

Testing ark-cli is essential as it is the interface for utilizing various functionalities provided by ark-rust crates.
Without proper testing, there's a risk of undetected issues between different crates.

Proposal:

1. Basic Use Case Shell Scripts:
   • Shell scripts that showcase core ark-cli functionalities.
   • These scripts should represent typical user scenarios for interacting with ark-cli.
2. Issue fs-index: Filesystem monitoring using notify-rs #21 Test Script (upon merge):
   • This script should verify ark-cli watch
