Moe Charm (CI) 3b4449d773 Phase v4-mid-1: C6-only v4 route + page_meta_of() Fail-Fast validation ...

Implementation:
- SMALL_SEGMENT_V4_* constants (SIZE=2MiB, PAGE_SIZE=64KiB, MAGIC=0xDEADBEEF)
- smallsegment_v4_page_meta_of(): O(1) mask+shift lookup with magic validation
  - Computes segment base: addr & ~(2MiB - 1)
  - Verifies SmallSegment magic number
  - Calculates page_idx: (addr - seg_base) >> PAGE_SHIFT (16)
  - Returns non-NULL sentinel for now (full page_meta[] in Phase v4-mid-2)

Stubs for C6-only phase:
- small_heap_alloc_fast_v4(): C6 returns NULL → pool v1 fallback
- small_heap_free_fast_v4(): C6 calls page_meta_of() for Fail-Fast, then pool v1 fallback

Documentation:
- ENV_PROFILE_PRESETS.md: Add "C6_ONLY_SMALLOBJECT_V4" research profile
  - HAKMEM_SMALL_HEAP_V4_ENABLED=1, HAKMEM_SMALL_HEAP_V4_CLASSES=0x40
  - Expected: Throughput ≈ 28–29M ops/s (same as v1)

Build:
- ビルド成功（警告のみ）
- Backward compatible, alloc/free stubs fall back to pool v1

Sanity:
- C6-heavy with v4 opt-in: segv/assert なし
- page_meta_of() lookup working correctly
- Performance unchanged (expected for stub phase)

Status:
- C6-only v4 route now available via ENV opt-in
- Phase v4-mid-2: SmallHeapCtx v4 full implementation with A/B
