docs(state): update STATE.scm with performance benchmarking completion

Added session-history entry for performance optimization:
- Comprehensive performance benchmarking (1,047 lines)
- Criterion.rs benchmarks with 9 categories
- Automated profiling (CPU, memory, perf)
- Performance guide with optimization strategies
- All performance targets exceeded

Updated project status:
- Overall completion: 95% → 98%
- Cleared all this-week priorities

Updated working-features:
- Comprehensive performance benchmarking (9 categories)
- Automated profiling (CPU flamegraph, memory, perf)
- Performance targets and monitoring

Updated critical-next-actions:
- Cleared performance benchmarking ✅
- Cleared all this-week priorities ✅
- Next: self-healing, analytics, CI/CD integration
