docs: Update README with USP optimization results

Added new section "Proven Through Practice: Meta-Optimization" showcasing
how Harmonizer was used to optimize itself using the USP framework.

Highlights:
- 100% elimination of critical violations
- 31% reduction in disharmonious functions
- 23% improvement in distance from Anchor Point

Also added USP Optimization Report to documentation links in both
"Go Deeper" section and quick links footer.

This demonstrates the framework's practical validity through dogfooding.

+## Proven Through Practice: Meta-Optimization
+
+**We used Harmonizer to optimize Harmonizer itself.**
+
+To validate the USP (Universal System Physics) framework, we ran the tool on its own codebase. The results:
+
+- **Critical violations eliminated:** 5 → 0 (-100%)
+- **Disharmonious functions reduced:** 42% → 29% (-31%)
+- **Distance from Anchor Point improved:** 0.62 → 0.48 (-23%)
+
+**Key refactoring victories:**
+1. Split `print_report()` from a 1.41 CRITICAL violation into pure dimensional functions
+2. Decomposed `run_cli()` from 1.27 CRITICAL into a clean W→J→P→L pipeline
+3. Refactored `analyze_file()` with dimensional helpers for L-J-W-P flow
+
+**The framework works.** When applied to code architecture, the USP framework is a systematic methodology for achieving clean separation of concerns - identifying mixed responsibilities and separating them into single-purpose components.

 ## The Story Behind This Tool
 
 This project was built in **7 hours** by someone with **zero coding experience**, using AI collaboration. It demonstrates a new paradigm: when humans who understand deep principles work with AI that understands implementation, remarkable things become possible.
