Moe Charm (CI) 3c6c76cb11 Fix: Restore headers in box_carve_and_push_with_freelist()
Root cause identified by Task exploration agent:
- box_carve_and_push_with_freelist() pops blocks from slab
  freelist without restoring headers before pushing to TLS SLL
- Freelist blocks have stale data at offset 0
- When popped from TLS SLL, header validation fails
- Error: [TLS_SLL_HDR_RESET] cls=1 got=0x00 expect=0xa1

Fix applied:
1. Added HEADER_MAGIC restoration before tls_sll_push()
   in box_carve_and_push_with_freelist() (carve_push_box.c:193-198)
2. Added tiny_region_id.h include for HEADER_MAGIC definition

Results:
- 20 threads: Header corruption ELIMINATED ✓
- 4 threads: Still shows 1 corruption (partial fix)
- Suggests multiple freelist pop paths exist

Additional work needed:
- Check hakmem_tiny_alloc_new.inc freelist pops
- Verify all freelist → TLS SLL paths write headers

Reference:
Same pattern as tiny_superslab_alloc.inc.h:159-169 (correct impl)
