2.1.0

Added

• Auto-reload after 4 hours idle — after four hours without a keypress or
  scroll, YAWF silently reloads WhatsApp Web to reclaim the JS heap that
  accumulates from high-volume group chats. Messages reload from local IndexedDB
  in seconds; no re-link or server re-fetch required. Any interaction resets the
  clock so active sessions are never interrupted.
• Tray → Refresh — new menu item in the system-tray context menu for
  on-demand reload when you notice slowdown, without waiting for the idle timer.

Fixed

• WebKit memory pressure thresholds were set against an 8 GB base limit, meaning
  they never triggered on real hardware before the OS OOM-killed the web process
  at ~3 GB. Limit is now derived from /proc/meminfo (40% of physical RAM,
  clamped to 2–4 GB) so cache-release fires at ~2 GB on an 8 GB machine.
• Memory pressure is now polled every 5 s instead of every 30 s, so spikes from
  message storms are caught before they become fatal.
• Enabled JavaScriptCore concurrent GC (reduces main-thread stall during message
  storms) and generational GC (short-lived message objects collected cheaply).
• WebInspector bundle no longer loaded in normal use; set YAWF_DEVTOOLS=1 to
  re-enable it for debugging.
• Unresponsive web-process detection tightened from 5 s to 3 s.
