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

Phase 4b: Add master debug control (HAKMEM_DEBUG_ALL/LEVEL)

Add centralized debug control system that allows enabling all debug
modules at once, while maintaining backwards compatibility with
individual module ENVs.

New file: core/hakmem_debug_master.h
- HAKMEM_DEBUG_ALL=1: Enable all debug modules
- HAKMEM_DEBUG_LEVEL=N: Set debug level (0=off, 1=critical, 2=normal, 3=verbose)
- HAKMEM_QUIET=1: Suppress all debug (highest priority)
- hak_debug_check(): Check if module should enable debug
- hak_is_quiet(): Quick check for quiet mode

Priority order:
1. HAKMEM_QUIET=1 → suppress all
2. Specific module ENV (e.g., HAKMEM_SFC_DEBUG=1)
3. HAKMEM_DEBUG_ALL=1
4. HAKMEM_DEBUG_LEVEL >= threshold

Updated files:
- core/hakmem_elo.c: Use hak_is_quiet() instead of local implementation
- core/hakmem_shared_pool.c: Use hak_debug_check() for lock stats

Performance: No regression (71.5M ops/s maintained)
