Zig Resource Cleanup: defer, errdefer, Files, Sockets, and Allocators

A practical two-hour session on Zig Resource Cleanup, focused on defer, errdefer, Files, Sockets, and Allocators. Zig is used realistically for systems tooling, C interop, parsing, build workflows, and performance-minded components rather than pretending it is a full web platform.

Audience: entry-level and intermediate developers who want a practical engineering session, not a language tour.

Outcomes:

• Explain the practical boundaries of Zig Resource Cleanup
• Apply defer in a small working example
• Apply errdefer in a small working example
• Apply Files in a small working example

Format: two hours with a short framing walkthrough, a concrete example, discussion of tradeoffs, and a closing checklist for practice.
