fix(review): a review with a control that did not run stops a merge

Operator decision 2026-10-06. Before, a WARN that existed only because a
reviewer or engine never reported (e.g. /security-review without an origin
remote) mapped to verdict-gate exit 0, so a review nobody performed in full
was green. Now `missing-reviewer:` / `unattributable-payload` in the JSON
block's allow_blocked_by is exit 2 (could not decide, never green); a WARN
for a MAJOR or a set-aside finding still passes with its reasons. A 1.1
review must carry allow_blocked_by.

**Consumer:** `/trekplan` Phase 1 when `--brief review.md` is supplied and the consumer detects `type: trekreview` in frontmatter. The plan command branches into a remediation-plan path: BLOCKER + MAJOR findings become plan goals, the produced `plan.md` carries a `source_findings: [<id>, ...]` frontmatter list as the audit trail back to the consumed findings. MINOR + SUGGESTION are skipped for plan-input. Since 1.1 every BLOCKER is also written as a numbered `### Step R<n>` under `## Remediation Steps` (Files · Source finding · Test first · Verify · On failure), so a consumer can append it as a plan step without rewording it.
**Second consumer — the verdict gate (K7, 1.1):** `lib/review/verdict-gate.mjs <review.md>` reads the frontmatter `verdict` and exits 0 = ALLOW/WARN, 1 = BLOCK, 2 = could not decide. Exit 2 is never green: a missing file, a missing or unknown verdict, two verdict lines, a trailing JSON block that is not the last fence or lacks `verdict`/`counts`/`findings`, and a file whose JSON block, `## Findings (BLOCKER)` section or finding-id list contradicts a greener verdict all land there. Exactly one file per call. Whatever stops a merge or a release on a review reads this exit code, never a summary. Borrowed: the verdict goes to a file and a command gates on it (Kiro `feature-pipeline`); the executor reads the verdict but never writes it (Spec Kit).

**Path conventions:**
- Project-dir mode (recommended): `{project_dir}/review.md` (one per review iteration; subsequent runs overwrite atomically).
