refactor(review): compress unresolved-status prose to fit parity budget

After merging origin/main (v1.57.3.0), plan-devex-review exceeded the 1.05x
parity ratio vs the v1.53.0.0 baseline. Rather than rebase the baseline,
compressed the new prose to stay under the cap honestly: the report's
unresolved-status block (~32 -> ~9 lines) and the EXIT PLAN MODE GATE's
final-line check (~7 -> ~5 lines), plus the plan-devex-review review-log
step. All load-bearing rules and the exact gate-checkable tokens are
preserved; the static guards in gen-skill-docs.test.ts still pass.

-2. **Prior-reviews count:** the log stores only \\\`unresolved:N\\\` counts, and the current
-   review's row is already written before this report runs. Take the latest fresh row per
-   review skill (same 7-day window as the dashboard), DROP the current skill's row
-   entirely (do NOT backfill an older row for it), and sum \\\`unresolved\\\` across the
-   rest. Add the "+ N unresolved from prior reviews" bullet only when that sum is > 0.
-   Never sum all log rows — reruns would double-count.
-3. **Sentinel rule:** emit \\\`NO UNRESOLVED DECISIONS\\\` if and only if step 1 produced
