Phase v7-5b: C5+C6 multi-class expansion (+4.3% improvement)

- Add C5 (256B blocks) support alongside C6 (512B blocks)
- Same segment shared between C5/C6 (page_meta.class_idx distinguishes)
- SMALL_V7_CLASS_SUPPORTED() macro for class validation
- Extend small_v7_block_size() for C5 (switch statement)

A/B Result: C6-only v7 avg 7.64M ops/s → C5+C6 v7 avg 7.97M ops/s (+4.3%)
Criteria: C6 protected ✅, C5 net positive ✅, TLS bloat none ✅

ENV: HAKMEM_SMALL_HEAP_V7_CLASSES=0x60 (bit5+bit6)

Phase v7-2: SmallObject v7 C6-only implementation with RegionIdBox integration

- SmallSegment_v7: 2MiB segment with TLS slot and free page stack
- ColdIface_v7: Page refill/retire between HotBox and SegmentBox
- HotBox_v7: Full C6-only alloc/free with header writing (HEADER_MAGIC|class_idx)
- Free path early-exit: Check v7 route BEFORE ss_fast_lookup (separate mmap segment)
- RegionIdBox: Register v7 segment for ptr->region lookup
- Benchmark: v7 ON ~54.5M ops/s (-7% overhead vs 58.6M legacy baseline)

v7 correctly balances alloc/free counts and page lifecycle.
RegionIdBox overhead identified as primary cost driver.
