Pull request overview

Upgrades the integrated browser’s Playwright dependency to v1.59.1 and updates the page summarization implementation to use the newer public Playwright API for AI-oriented accessibility snapshots.

Changes:

• Bump playwright-core to 1.59.1 and @playwright/test to ^1.59.1.
• Replace usage of the hidden _snapshotForAI(...) API (and its local type augmentation) with page.ariaSnapshot({ mode: 'ai' }).
• Simplify summary snapshot handling to treat the returned snapshot as a single trimmed string.
