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.
