The 24-hour timeout was still not being respected - sessions were being
killed after ~14 minutes. Using Timeout.InfiniteTimeSpan completely
disables idle-based session pruning in the SDK's IdleTrackingBackgroundService.
This makes the MCP server bulletproof against session drops during long
periods of inactivity (e.g., when users are discussing/planning before
making tool calls).
