Zig Async I/O Skill (0.16.0+)

Overview

Zig 0.16.0 introduces a redesigned async I/O system based on the std.Io interface. Unlike the old async/await (removed in 0.11), the new design decouples concurrency expression from execution models, allowing code to work optimally across synchronous, multi-threaded, and event-driven contexts.

Critical Concept: Asynchrony ≠ Concurrency

• async: Operations can proceed out-of-order (sequential awaiting is valid)
• concurrent: Operations must proceed simultaneously (requires parallelism)
