Rename RealTimeSearchTool → WeatherTool, fetch Balashikha weather via SearXNG

WeatherTool queries SearXNG with a fixed 'weather Balashikha Moscow now'
query instead of passing the user message as-is. SearXNG has external
internet access and returns snippets with actual current conditions.
Direct wttr.in fetch not possible — deepagents container has no external
internet routing.
