fix(chatgpt): drop unused second arg from getChatGPTImageAssets evaluate

[ele-yufo]

Summary

getChatGPTImageAssets passes the URL list both ways:

const urlsJson = JSON.stringify(urls);
return await page.evaluate(`
    (async (targetUrls) => { ... })(${urlsJson})   // ← inlined here
`, urls);                                          // ← also as a CDP arg

Browser bridge 1.7.x rejects the second form for string scripts:

page.evaluate string input does not accept args; use page.evaluate(fn, ...args) instead

So any opencli chatgpt image <prompt> that actually downloads the asset (i.e. without --sd true) fails with code: UNKNOWN.

Fix

Drop the trailing , urls argument. The URLs are already inlined via the ${urlsJson} template substitution, so no semantic change — only the redundant + now-invalid CDP arg is removed.

Root cause

The redundant arg was harmless in older bridge versions; the strict-mode guard was added in browser/utils.ts:

if (args.length > 0) {
    throw new Error('page.evaluate string input does not accept args; ...');
}

Validation

• npx tsc --noEmit clean
• npx vitest run --project adapter clis/chatgpt/ — 25/25 pass (3 files)
• Live: opencli chatgpt image "a fluffy orange cat" --op /tmp/x succeeds end-to-end after the fix (fails before with the error above)

Scope

Single-line change in clis/chatgpt/utils.js. No new tests — the existing image.test.js mocks getChatGPTImageAssets, so this codepath is only exercised against a live browser. Happy to add an integration-style assertion if the reviewer prefers.
