Patch Changes

• 6daad22: ### Bug Fixes

  • WebSocket keepalive for remote browsers - Added WebSocket Ping frames and TCP SO_KEEPALIVE to prevent CDP connections from being silently dropped by intermediate proxies (reverse proxies, load balancers, service meshes) during idle periods (#936)
  • XPath selector support - Fixed element resolution to correctly handle the xpath= selector prefix (#908)

  Performance

  • Fast-path for identical snapshots - Short-circuits the Myers diff algorithm when comparing a snapshot to itself, avoiding unnecessary computation in retry and loop workloads where repeated identical snapshots are common (#922)

  • Migrated page metadata from MDX files to layout.tsx (#904)
  • Added search functionality and color improvements to docs (#927)
  • Fixed desktop browser list in the iOS comparison table (#926)
