gh label pagination breaks visual-test workflow

[opencode-agent]

Issue created: #973

Diagnosis summary

• build-output.log was never produced because the game never ran.
• Actual failure: step 8 Ensure visual-test label exists at .github/workflows/visual-test.yml:55-66 aborted the job.
• Root cause: gh label list paginates at 30; the repo has 41 labels and run-visual-test is at index 31. The precheck at visual-test.yml:62 reports it missing, the subsequent gh label create errors with label with name "run-visual-test" already exists; use --force ..., and the step exits 1, skipping Lavapipe setup and the screenshot run.
• No Vulkan/swapchain/screenshot code was ever reached: vulkan_swapchain.zig:127, app.zig:268-276, modules/game-ui/src/screens/home.zig:33-40, and screenshot.zig:24-44 were not executed.
• This is a recurring regression of issues [Visual Test] Label pagination aborts workflow before screenshot capture #968 and [Visual Test] Label preflight pagination aborts workflow before screenshot capture on run #30887567592 #970 (the visual-test.yml step has not been modified since the only dev commit, 8d205ff).
• Suggested fix: replace the conditional with two unconditional gh label create ... --force calls (full snippet in the issue body).
