Phase 70-0: Infrastructure prep for refill tuning (Observability + WarmPool Sizing)

Browse Source 
- Observability Fix: Enabled unified cache hit/miss stats in release builds when HAKMEM_UNIFIED_CACHE_STATS_COMPILED is set.
- WarmPool Sizing: Decoupled hardcoded '12' from prefill logic; now uses TINY_WARM_POOL_DEFAULT_PER_CLASS macro and respects ENV overrides.
- Increased TINY_WARM_POOL_MAX_PER_CLASS to 32 to support wider ENV sweeps.
- Added unified_cache_auto_stats destructor to dump metrics at exit (replacing debug print hack).
