fix(rocm): correct runtime capability and resolution semantics

[nekomario28]

Review/delivery carrier for upstream FlashML-org#132

This PR is an upstream FlashML-org#132 correction carrier, not a merge target for this fork's diverged main.

Base review/pr132-head-45417560 is an immutable snapshot of FlashML-org/FreeToken#132 head 45417560beeba896a9b0866e50154d2a7a320b8b. The head commit bbeb65e88201d23604bc6a4c489c881e686dd27a is its direct one-commit child.

Corrections

1. Use registered-host-pointer capability semantics rather than unified addressing as the proxy for host-pointer identity capability.
2. Resolve versioned libamdhip64.so.* numerically rather than lexically, sharing the selector across setup/build and JIT discovery.
3. Key project-owned HIP runtime compatibility links by runtime origin so persistent caches cannot silently retain an old SDK/image target.

Focused regression coverage for the three contracts is included in the same commit.

Existing gfx1101 evidence

Previously validated after composition on RX 7800 XT / gfx1101 with PyTorch 2.11.0+rocm7.2, HIP 7.2.26015, TVM-FFI 0.1.13.post3:

• focused sandbox suite: 11 passed, 3 skipped
• focused physical suite: 14 passed
• _pinned_tensor + _cpu_moe build: PASS
• physical extension load: PASS
• compileall: PASS
• git diff --check: PASS

Claim boundary: focused runtime/build correctness only; no full model serving, NVIDIA parity, multi-GPU RCCL, RDNA4, or performance claim.

Delivery status

Preferred delivery is to the existing upstream FlashML-org#132 author branch/conversation, preserving contributor lineage. Direct cross-fork PR/comment delivery via the currently connected GitHub integration is blocked with 403 Resource not accessible by integration. This carrier keeps the exact minimal delta ready for an authorized GitHub/CLI path.
