Add Larson performance analysis and optimized profile

Ultrathink analysis reveals root cause of 4x performance gap:

Key Findings:
- Single-thread: HAKMEM 0.46M ops/s vs system 4.29M ops/s (10.7%)
- Multi-thread: HAKMEM 1.81M ops/s vs system 7.23M ops/s (25.0%)
- Root cause: malloc() entry point has 8+ branch checks
- Bottleneck: Fast Path is structurally complex vs system tcache

Files Added:
- LARSON_PERFORMANCE_ANALYSIS_2025_11_05.md: Detailed analysis with 3 optimization strategies
- scripts/profiles/tinyhot_optimized.env: CLAUDE.md-based optimized config

Proposed Solutions:
- Option A: Optimize malloc() guard checks (+200-400% expected)
- Option B: Improve refill efficiency (+30-50% expected)
- Option C: Complete Fast Path simplification (+400-800% expected)

Target: Achieve 60-80% of system malloc performance

Debug Counters Implementation - Clean History

Major Features:
- Debug counter infrastructure for Refill Stage tracking
- Free Pipeline counters (ss_local, ss_remote, tls_sll)
- Diagnostic counters for early return analysis
- Unified larson.sh benchmark runner with profiles
- Phase 6-3 regression analysis documentation

Bug Fixes:
- Fix SuperSlab disabled by default (HAKMEM_TINY_USE_SUPERSLAB)
- Fix profile variable naming consistency
- Add .gitignore patterns for large files

Performance:
- Phase 6-3: 4.79 M ops/s (has OOM risk)
- With SuperSlab: 3.13 M ops/s (+19% improvement)

This is a clean repository without large log files.
