feat(a5): run Qwen3 decode with host graph execution

[doraemonmj]

What

• migrate the existing A5 Qwen3-14B decode orchestration from tensormap_and_ringbuffer to host_build_graph
• reuse all 37 A5 TMR incore sources, input generation, and golden implementation
• record one decoder layer as an HBG Graph and replay its cached definition for the remaining 39 layers
• reuse ping-pong hidden-state buffers and shared BF16/FP32 scratch arenas across layers

Testing

• single-layer migration: task_20260814_095742_232203113705 — 1 passed
• full 40-layer Graph execution: task_20260814_095945_234090013318 — 1 passed on Ascend950PR_9579
• pre-commit hooks — passed

Warning

Review limit reached

@doraemonmj, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 49 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
