feat: Add v1.2 features - Exit codes, JSON output, and enhanced badges

Implemented three major quick wins for v1.2:

1. EXIT CODES FOR CI/CD 🚀
   - Returns meaningful exit codes based on severity:
     * 0 = All harmonious (excellent or low severity)
     * 1 = Medium severity found (0.5-0.8)
     * 2 = High severity found (0.8-1.2)
     * 3 = Critical severity found (≥ 1.2)
   - Enables automated quality gates in CI/CD pipelines
   - Build fails automatically on high/critical disharmony
   - Perfect for GitHub Actions, GitLab CI, Jenkins, etc.

2. JSON OUTPUT FORMAT 📊
   - New --format json option for machine-readable output
   - Structured data includes:
     * Version and threshold information
     * Per-file function analysis with scores
     * Severity levels (excellent, low, medium, high, critical)
     * Summary statistics across all files
   - Enables tool integration (IDEs, dashboards, analytics)
   - Quiet mode automatically enabled for JSON output

3. ENHANCED COMMAND-LINE INTERFACE
   - Added argparse for professional CLI experience
   - New flags:
     * --format {text,json} - Choose output format
     * --threshold FLOAT - Custom disharmony threshold
     * --version - Show version number
     * --help - Comprehensive help with examples
   - Improved help text with usage examples
   - Better error messages

4. ENHANCED README BADGES
   - Added CI status badge (links to Actions)
   - Added version badge (links to CHANGELOG)
   - Added test pass rate badge (20 tests passing)
   - Added harmony score badge (meta - tool analyzing itself!)
   - All badges clickable with relevant links

Technical Implementation:
- get_severity() method maps scores to severity levels
- get_highest_severity_code() returns appropriate exit code
- print_json_report() generates structured JSON output
- Quiet mode suppresses text output when using JSON
- All changes backward compatible with existing usage

Documentation Updates:
- CHANGELOG.md: Added v1.2.0 release notes
- QUICK_REFERENCE.md: Added Advanced Options section with:
  * JSON output examples
  * Exit code reference table
  * CI/CD usage examples
- README.md: Enhanced badge section

Testing:
- All 20 existing tests still pass
- Manual testing confirms:
  * Exit codes work correctly (tested with examples/test_code.py → exit 3)
  * JSON output is valid and well-structured
  * Text output unchanged and working
  * --version and --help flags work
- Black formatting applied

Breaking Changes: None
- Existing usage (harmonizer file.py) works unchanged
- Default behavior is text output, exit code 0 for harmonious code
- Fully backward compatible

This release makes Harmonizer production-ready for CI/CD integration
and enables tool ecosystem development. 💛⚓
