Subject: [PATCH 1/2] fix(opencode): system llvm for cargo-llvm-cov (v3
 concurrency)

Same fix as #1081/#1072: install Debian llvm and export LLVM_COV/
LLVM_PROFDATA so OpenCode coverage-evidence can run cargo-llvm-cov on
Rust repos (e.g. TEPP#46) without rustup llvm-tools-preview.

#1081 concurrency group is held by a non-terminating cancelled model-pool
job; new PR number frees repository_dispatch concurrency.

Subject: [PATCH 2/2] ci: re-queue exact-head review after Strix green

All required checks green including Strix. Trigger pull_request_target
merge-scheduler path so OpenCode can APPROVE llvm bake for TEPP#46.
