#22782: fix(browser): respect fullPage option in screenshot captureBeyondViewport

## Summary Fixes viewport-only screenshots capturing the entire page because `captureBeyondViewport` was hardcoded to `true`. ## Problem In `src/browser/cdp.ts`, the CDP `Page.captureScreenshot` call always uses `captureBeyondViewport: true`, ignoring the `fullPage` option. This means `fullPage: false` screenshots still capture content beyond the viewport. ## Fix Changed `captureBeyondViewport: true` to `captureBeyondViewport: opts.fullPage ?? false`. **1 file changed**, 1 line modified. Fixes #17476 ## Scope Single line change in `src/browser/cdp.ts`. ## AI Assistance Claude Code assisted with identifying the hardcoded parameter. ## Author **Miloud Belarebia** — [@miloudbelarebia](https://github.com/miloudbelarebia) <!-- greptile_comment --> <h3>Greptile Summary</h3> Fixed a bug where viewport-only screenshots (`fullPage: false`) were incorrectly capturing the entire page. The `captureScreenshot` function in `src/browser/cdp.ts:75` was hardcoded with `captureBeyondViewport: true`, which caused it to ignore the `fullPage` option. The fix changes this to `captureBeyondViewport: opts.fullPage ?? false`, ensuring that: - When `fullPage: true` → captures beyond viewport with full page dimensions - When `fullPage: false` or undefined → captures only the visible viewport This is a minimal, targeted fix that directly addresses the root cause. <h3>Confidence Score: 5/5</h3> - This PR is safe to merge with minimal risk - The change is a single-line fix that corrects a clear logic error where a hardcoded boolean value was preventing the `fullPage` option from working as intended. The fix properly respects the `fullPage` parameter using standard nullish coalescing, maintains backward compatibility (defaults to false when undefined), and aligns with the existing logic that sets clip regions based on `fullPage`. No new dependencies, no breaking changes, and addresses the reported issue #17476 directly. - No files require special attention _{Last reviewed commit: 5e59b43} <!-- greptile_other_comments_section --> <!-- /greptile_comment -->
