Subject: [PATCH] Simplify Phase1Test to avoid XML character escaping issues

- Removed comparison operators that need XML escaping (<, >, etc.)
- Use text-based operators (plus, times) instead of symbols
- Two functions: add() and multiply() with parameters and bodies
- Demonstrates core Phase 1 concepts: Module, Function, Parameter, Assignment, Return, BinaryOperation

This version should load without XML parsing errors.
