Analytics not reporting for versions >0.1.4

This might be related to using the new dart run <package>@ feature, possibly the environment variables are not being propagated properly there.

I confirmed the analytics variable is not set in this mode, added some logging for the parsed tool and analytics info running each way:

dart run pkgs/dart_mcp_server/bin/dart_mcp_server.dart 
tool: DashTool.dartTool, analytics: Instance of 'AnalyticsImpl', okToSend: true

dart run dart_mcp_server@{\"path\":\"$HOME/ai/pkgs/dart_mcp_server\"}
tool: null, analytics: null, okToSend: null
