Filed issue #970: label preflight pagination aborts run.

[opencode-agent]

Filed #970 with label visual-test.

Diagnosis: The failure is at .github/workflows/visual-test.yml:55-66 (Ensure visual-test label exists), not in Vulkan/screenshot code. gh label list returns only 30 labels (default pagination) but the repo has 41, so run-visual-test (index 31) is invisible to the precheck; the subsequent gh label create then fails with label with name "run-visual-test" already exists, the step exits 1 under set -euo pipefail, and the rest of the job (Lavapipe setup, screenshot capture, golden diff) is skipped.

Evidence:

• build-output.log missing from workspace (game never ran)
• weston.log shows weston started and was killed by SIGTERM from the Stop headless Wayland compositor step (if: always())
• gh label list --repo OpenStaticFish/ZigCraft returns 30, --limit 100 returns 41
• weston.log:62 caught signal 15 is the stop action, not a weston crash
• Same root cause as the still-open issue [Visual Test] Label pagination aborts workflow before screenshot capture #968 (run #30795834741); the step has not been modified since the devenv migration commit 8d205ff, so the regression is recurring

The Zig paths (vulkan_swapchain.zig:127, app.zig:268-276, screenshot.zig:24-44) were never entered. Also noted that the diagnose prompt is stale (.ppm vs the workflow's .png; old src/game/screens/home.zig vs the current modules/game-ui/src/screens/home.zig).
