Box TLS-SLL: fix splice head normalization and remove false misalignment guard; add header-aware linear link instrumentation; log splice details in debug.\n\n- Normalize head before publishing to TLS SLL (avoid user-ptr head)\n- Remove size-mod alignment guard (stride!=size); keep small-ptr fail-fast only\n- Drop heuristic base normalization to avoid corrupting base\n- Add [LINEAR_LINK]/[SPLICE_LINK]/[SPLICE_SET_HEAD] debug logs (debug-only)\n- Verified debug build on bench_fixed_size_hakmem with visible carve/splice traces
