exec_os: enrich all stubs to bootcamp-quality reference articles

Browse source 
Complete rewrite of 14 exec_os articles from stubs to comprehensive
deep-dive technical references with architecture diagrams, pitfalls,
and best practices.

New: multitasking.md (scheduler, IPC, memory safety, real-world scenarios)
Enriched: exec_base, tasks_processes, library_system, library_vectors,
interrupts, exceptions_traps, memory_management, message_ports, signals,
semaphores, io_requests, lists_nodes, resident_modules

Updated indexes: 06_exec_os/README.md, root README.md
