Agent Skills: zig-expert

Write idiomatic Zig code following the Zen of Zig philosophy. Use for systems programming with Zig (.zig files), covering manual memory management with allocators, error unions and explicit error handling, compile-time programming (comptime), data-oriented design, and the new async/Io model. Applies functional programming parallels (Result types, ADTs, explicit effects) for C-free systems development.
