Module process 

Process management module

This module provides the core process and thread management functionality for the VeridianOS microkernel, including:

• Process Control Block (PCB) management
• Thread creation and management
• Process lifecycle (creation, termination, state transitions)
• Global process table
• Memory space management
• Capability integration
