Enhanced Output Formatting

Difficulty: ⭐⭐⭐ (Medium)
Dependencies: Issue #5
Component: CLI Interface

Description: Implement comprehensive output formatting that supports multiple formats for different use cases and integrations. Create proper JSON output formatting with consistent structure and complete metadata for programmatic consumption, add YAML output support for configuration-friendly representation, and implement CSV export functionality for spreadsheet analysis and reporting. Enhance table formatting with column width optimization, alignment improvements, and color coding for better readability in terminal output. Support custom output templates using Go's text/template package for user-defined formats, add output validation to ensure all required fields are present, and implement output streaming for large result sets to avoid memory issues. Include output format detection from file extensions when writing to files, add pretty-printing options for human-readable output, and support output compression for large exports.

Acceptance Criteria:

• Implement proper JSON output formatting with pretty-print
• Add YAML output support with proper indentation
• Implement CSV export functionality with header row
• Add table formatting improvements (colors, alignment)
• Support custom output templates with examples
• Add output validation and error handling
