Implement benchkit compliance tasks 033-035

- Task 033: Fix generic section naming violations
  - Updated documentation to use specific section names instead of generic ones
  - Replaced "Performance Results" with "Cache Optimization Performance Results"
  - Updated "Benchmarks & Validation" to "SIMD Performance Validation"

- Task 034: Replace custom scripts with cargo bench workflow
  - Prioritized cargo bench commands over shell scripts in documentation
  - Marked shell scripts as deprecated with migration guidance
  - Updated all benchmark documentation to use standard Rust workflow

- Task 035: Implement statistical significance testing
  - Added statistical_analysis feature to benchkit dependency
  - Enhanced string interning benchmark with proper statistical analysis
  - Implemented 25+ sample measurements with confidence intervals
  - Added reliability assessment and statistical power analysis
  - Report 95% confidence intervals instead of point estimates
