// Package main implements a sub-process with command-line management and tracing.
// It showcases how to:
// 1. Create a sub-process command
// 2. Receive and handle trace context from parent
// 3. Execute sub-process logic
// 4. Report process status through logging
//
// This example demonstrates trace context propagation in a child process.
