Refactor CLI Module for Better Maintainability

[PaperMtn]

Problem

The current cli.py is a large monolithic file (4000+ lines) that handles all command-line functionality. This makes it difficult to:

• Maintain and update specific commands
• Add new commands without increasing complexity
• Onboard new developers to add new functionality

Proposed Changes

Refactor the CLI module into a modular structure:

src/secops/cli/
├── __init__.py
├── __main.py__            # Main CLI entry point
├── commands/             # Command handlers
│   ├── __init__.py
│   ├── config.py         # Config commands
│   ├── search.py         # Search commands
│   ├── rule.py           # Rule management
│   ├── feed.py           # Feed management
│   ├── export.py         # Data export
│   ├── data_table.py     # Data table operations
│   ├── reference_list.py # Reference list operations
│   └── ...               # etc.
└── utils/                # Shared utility functions
    ├── __init__.py
    ├── formatters.py  
    ├── config_utils.py     
    └── time_utils.py     

Key Benefits:

• Improved Maintainability: Smaller, focused files are easier to understand and modify
• Better Organisation: Logical grouping of related functionality
• Faster Development: New commands can be added without navigating a large file

Migration:

• Backward compatibility will be maintained
• Existing scripts using secops.cli will continue to work
• New code should use the modular structure
