fix(web): prevent preview iframe from stealing focus on load (#2792)
* Fix preview iframe focus stealing

* Fix preview focus guard for URL-loaded HTML previews

Focus guard was only injected via the srcdoc path, but the default
URL-load path bypasses buildSrcdoc entirely. Add htmlNeedsFocusGuard
detection so focus-stealing HTML is routed through srcdoc where the
guard can suppress window.focus/element.focus calls.

* Widen focus guard detector to cover all .focus() call patterns

The previous regex only matched window.focus() and document.focus(),
missing document.body.focus(), querySelector().focus(), and other
chained focus calls. Broaden to match any `.focus(` so the default
URL-loaded preview path is forced to srcDoc for all focus-stealing HTML.

* Conservatively force srcDoc for HTML with external script references

When the HTML contains <script src=...>, we cannot inspect the linked
file for focus-stealing calls. Force the srcDoc path so the focus guard
intercepts any .focus() calls from external scripts.
