Zig Debugging

This covers the full debugging toolkit for Zig programs: running GDB and LLDB sessions with the right breakpoints, decoding Zig's panic messages and error return traces, using std.debug.print for printf-style debugging, and setting up VS Code with launch configurations. The error return trace section is especially useful since Zig's try-chain tracking isn't immediately obvious to newcomers. It walks through interpreting stack traces, explains common panic messages like index out of bounds and integer overflow, and shows how to configure debug builds and logging levels. Reach for this when you're staring at a cryptic panic or need to step through Zig code line by line.
