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
