fix(opencode): bake llvm tools for Rust coverage-evidence

[seonghobae]

Summary

• OpenCode Review Dispatch coverage-evidence fails on Rust repos (e.g. TEPP#46) with:
  error: failed to find llvm-tools-preview
• Offline image had cargo-llvm-cov + Debian rustc/cargo but no llvm-cov/llvm-profdata.
• Install llvm in the coverage image and export LLVM_COV/LLVM_PROFDATA from ensure_rust_toolchain.

Unblocks

• TEPP commercialization serial PR Ignore transient governance helper cancellations #46 (exact-head Rust CI already green; blocked only on OpenCode primary APPROVE).

Test plan

• Merge this PR
• Re-dispatch OpenCode Review for TEPP#46 current head
• coverage-evidence no longer fails on missing llvm tools

Warning

Review limit reached

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

Next review available in: 5 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

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.

@opencode-agent review

Please APPROVE exact head 7badfd61e0031e632ddcf9394ba21500097cb7ee if the llvm bake is sound. This unblocks Rust coverage-evidence (TEPP #46 OpenCode APPROVE). Last pusher is seonghobae; no self-approve.

[seonghobae]

@opencode-agent @cwl-noema-review please review exact head 7badfd6.

This unblocks TEPP#46 OpenCode primary APPROVE: coverage-evidence was failing with missing llvm-tools-preview / LLVM_COV. This PR bakes Debian llvm into the offline coverage image and exports LLVM_COV/LLVM_PROFDATA.

Strix on the prior attempt was NIM 429 then runner cancel (infra), not a finding. Requeued.

[seonghobae]

@opencode-agent review exact head 7badfd61e0031e632ddcf9394ba21500097cb7ee.

Required checks no longer list Strix as in progress. Remaining merge 405 is last-pusher approval only. Please APPROVE this llvm bake if sound so TEPP #46 can get a current-head OpenCode APPROVE. No self-approve.

[seonghobae]

Hourly: Strix green; OpenCode Review Dispatch at coverage-evidence waiting on runners. All other checks green. Need independent APPROVE then merge to unblock TEPP#46 llvm-tools.

Head 7badfd6. No self-approve.

[seonghobae]

Hourly: All required checks green (incl. Strix). OpenCode Review Dispatch coverage-evidence success on this head; opencode-review job still in_progress (~30m+, runner 1000965167) at https://github.com/ContextualWisdomLab/.github/actions/runs/31987744089

.github ruleset needs 2 approving reviews + last-push approval (author/last pusher is seonghobae). @opencode-agent @cwl-noema-review please complete APPROVE on 7badfd6 when review finishes. Unblocks TEPP#46 llvm-tools OpenCode path.

[seonghobae]

Hourly: Force-cancelled hung OpenCode run; redispatched via merge scheduler.

New OpenCode Review Dispatch https://github.com/ContextualWisdomLab/.github/actions/runs/31996005046 — coverage-evidence success, opencode-review in_progress.

Ruleset: 2 APPROVEs + last-push approval (pusher seonghobae). @opencode-agent @cwl-noema-review please APPROVE 7badfd6 when complete. Unblocks TEPP#46.
