Implement Error Handling and Input Validation in PSAT

[milindmore22]

Describe the bug
Currently, the PSAT and PSAT CLI might not be catching potential errors during command execution. This can lead to unexpected behavior and frustration for users as reported by users in #600 and #582 (comment)

Additionally, the CLI may not be validating user input before processing it. This can result in errors further down the line and make it difficult for users to understand why their commands are failing.

• Implement error handling mechanisms to catch exceptions and other issues that arise during command execution.
• Provide informative and user-friendly error messages that clearly explain the problem encountered.
• Validate user input before processing commands. This could involve checking for data types, required parameters, and valid ranges.
• Offer suggestions ( like available option ) for correcting invalid input to guide users towards successful commands.

Desktop (please complete the following information):

• OS: Windows
• Browser CLI
• Version 0.6.0
