Moe Charm (CI) 3f461ba25f Cleanup: Consolidate debug ENV vars to HAKMEM_DEBUG_LEVEL 
Integrated 4 new debug environment variables added during bug fixes
into the existing unified HAKMEM_DEBUG_LEVEL system (expanded to 0-5 levels).

Changes:

1. Expanded HAKMEM_DEBUG_LEVEL from 0-3 to 0-5 levels:
   - 0 = OFF (production)
   - 1 = ERROR (critical errors)
   - 2 = WARN (warnings)
   - 3 = INFO (allocation paths, header validation, stats)
   - 4 = DEBUG (guard instrumentation, failfast)
   - 5 = TRACE (verbose tracing)

2. Integrated 4 environment variables:
   - HAKMEM_ALLOC_PATH_TRACE → HAKMEM_DEBUG_LEVEL >= 3 (INFO)
   - HAKMEM_TINY_SLL_VALIDATE_HDR → HAKMEM_DEBUG_LEVEL >= 3 (INFO)
   - HAKMEM_TINY_REFILL_FAILFAST → HAKMEM_DEBUG_LEVEL >= 4 (DEBUG)
   - HAKMEM_TINY_GUARD → HAKMEM_DEBUG_LEVEL >= 4 (DEBUG)

3. Kept 2 special-purpose variables (fine-grained control):
   - HAKMEM_TINY_GUARD_CLASS (target class for guard)
   - HAKMEM_TINY_GUARD_MAX (max guard events)

4. Backward compatibility:
   - Legacy ENV vars still work via hak_debug_check_level()
   - New code uses unified system
   - No behavior changes for existing users

Updated files:
- core/hakmem_debug_master.h (level 0-5 expansion)
- core/hakmem_tiny_superslab_internal.h (alloc path trace)
- core/box/tls_sll_box.h (header validation)
- core/tiny_failfast.c (failfast level)
- core/tiny_refill_opt.h (failfast guard)
- core/hakmem_tiny_ace_guard_box.inc (guard enable)
- core/hakmem_tiny.c (include hakmem_debug_master.h)

Impact:
- Simpler debug control: HAKMEM_DEBUG_LEVEL=3 instead of 4 separate ENVs
- Easier to discover/use
- Consistent debug levels across codebase
- Reduces ENV variable proliferation (43+ vars surveyed)

Future work:
- Consolidate remaining 39+ debug variables (documented in survey)
- Gradual migration over 2-3 releases
