Moe Charm (CI) cd6507468e Fix critical SuperSlab accounting bug + ACE improvements 
Critical Bug Fix (OOM Root Cause):
- ss_remote_push() was missing ss_active_dec_one() call
- Cross-thread frees did not decrement total_active_blocks
- SuperSlabs appeared "full" even when empty
- hak_tiny_trim() could never free SuperSlabs → OOM
- Result: alloc=49,123 freed=0 bytes=103GB

One-Line Fix (core/hakmem_tiny_superslab.h:360):
+ ss_active_dec_one(ss);  // Decrement on cross-thread free

Impact:
- OOM eliminated (167GB VmSize → clean exit)
- SuperSlabs now properly freed
- Performance maintained: 4.19M ops/s (±0%)
- Memory leak fixed (freed: 0 → expected ~45,000+)

ACE Improvements:
- Set SUPERSLAB_LG_DEFAULT = 21 (2MB, was 1MB)
- g_ss_min_lg_env now uses SUPERSLAB_LG_DEFAULT
- hak_tiny_superslab_next_lg() fallback to default if uninitialized
- Centralized ACE constants in .h for easier tuning

Verification:
- Larson benchmark: Clean completion, no OOM
- Throughput: 4,192,124 ops/s (baseline maintained)

Root cause analysis by Task agent: Larson 50%+ cross-thread frees
triggered accounting leak, preventing SuperSlab reclamation.
