Detailed Description

Unified system bootstrapper for initialization and shutdown.

This header provides a unified bootstrapper that coordinates the initialization and shutdown of all system components through the service container.

Thread Safety:

• unified_bootstrapper is thread-safe for concurrent initialization checks.
• initialize() and shutdown() should be called from a single thread.
• Once initialized, services() can be called from any thread.

Signal Handling:

• Automatically registers handlers for SIGTERM and SIGINT.
• Graceful shutdown is triggered on signal receipt.
