pub async fn execute_in_container( &self, container_name: &str, command: &[String], ) -> Result<ExecutionResult>

Execute a command in a container with proper error handling and observability Core Team Compliance: Async for I/O operations, proper error handling, no unwrap/expect

This method creates a fresh container for each command execution, which is appropriate for testing scenarios where isolation is more important than performance.
