Module sched 

Process and thread scheduling module

Implements a multi-level scheduler with support for:

• Multiple scheduling algorithms (round-robin, priority, CFS)
• Real-time scheduling classes
• SMP load balancing
• CPU affinity
• Context switching for x86_64, AArch64, and RISC-V

This module is a facade that re-exports the public API from submodules:

• scheduler - Core scheduler algorithm and state
• task - Task control block and priority types
• metrics - Performance metrics and measurement
• smp - Symmetric multiprocessing support
• queue - Ready queue management
• numa - NUMA-aware scheduling
• [init] - Initialization and timer setup
• runtime - Scheduler execution loop and idle task
• process_compat - Process compatibility wrapper types
• ipc_blocking - IPC blocking/waking and wait queues
• task_management - Task creation, exit, and thread scheduling
• load_balance - Load balancing and task migration
