Both _get_page_content and _get_async_page_content use a while-True
loop that retries page.content() on PlaywrightError with no upper
bound. If the page is in a permanently broken state (crashed tab,
closed context), this loops forever and hangs the process.
Replace with a bounded for-loop (default 10 retries = 5s), returning
an empty string if all attempts fail. This preserves the existing
retry behavior for the transient Windows issue (playwright#16108)
while preventing hangs.
