Package Structure & Configuration Setup

Phase 1: Package Structure & Configuration

Convert the current script-based structure to a proper Python package suitable for PyPI distribution.

Tasks:

• Create domain_security_analyzer/ package directory
• Add __init__.py files for proper module structure
• Move domain_analyzer.py to domain_security_analyzer/analyzer.py
• Create domain_security_analyzer/__main__.py for CLI entry point
• Set up domain_security_analyzer/__version__.py for version management
• Create modern pyproject.toml configuration file
• Add MANIFEST.in to include documentation and data files
• Update requirements.txt with pinned versions for stability

Package Structure:

domain-security-analyzer/
├── domain_security_analyzer/
│   ├── __init__.py
│   ├── __main__.py
│   ├── __version__.py
│   ├── analyzer.py (main logic)
│   └── cli.py (command line interface)
├── scripts/
│   └── parked_domain_csv.py
├── docs/
├── pyproject.toml
├── MANIFEST.in
├── requirements.txt
└── README.md

CLI Entry Point:

• Package should be installable with: pip install domain-security-analyzer
• CLI accessible via: domain-analyzer --help
• Python module usage: python -m domain_security_analyzer

Acceptance Criteria:

• Package can be imported: from domain_security_analyzer import DomainAnalyzer
• CLI works via entry point: domain-analyzer examples/domains.txt output.csv
• All current functionality preserved (SRI scanning, DNS analysis, etc.)
• Tests pass with new structure
• Local installation works: pip install -e .

Priority: High - Blocks all other PyPI release tasks
