Moe Charm (CI) 7f9e4015da docs: Update ENV_VARS.md with Phase 3 additions

Added documentation for new environment variables and build flags:

Benchmark Environment Variables:
- HAKMEM_BENCH_FAST_FRONT: Enable ultra-fast header-based free path
- HAKMEM_BENCH_WARMUP: Warmup cycles before timed run
- HAKMEM_FREE_ROUTE_TRACE: Debug trace for free() routing
- HAKMEM_EXTERNAL_GUARD_LOG: ExternalGuard debug logging
- HAKMEM_EXTERNAL_GUARD_STATS: ExternalGuard statistics at exit

Build Flags:
- HAKMEM_TINY_SS_TRUST_MMAP_ZERO: mmap zero-trust optimization
  - Default: 0 (safe)
  - Performance: +5.93% on bench_tiny_hot (allocation-heavy)
  - Safety: Release-only, cache reuse always gets full memset
  - Location: core/hakmem_build_flags.h:170-180
  - Implementation: core/box/ss_allocation_box.c:37-78

Deprecated:
- HAKMEM_DISABLE_MINCORE_CHECK: Removed in Phase 3 (commit d78baf41c)

Each entry includes:
- Default value
- Usage example
- Effect description
- Source code location
- A/B testing guidance (where applicable)
