Resolve build process errors

Run the build and fix the errors

The user wants me to run the build and fix any errors. According to the AGENTS.md file, the build command is zig build.

I should:

  1. Use todo_write to plan this task
  2. Run the build
  3. See what errors come up
  4. Fix them

Let me start by creating a todo list and then running the build.

I'll run the build and fix any errors that come up.
