fix: resolve arithmetic operations after Copilot merge

Browse Source 
- Fix try_add/try_sub/try_mul/try_div method call errors
- Use helper functions instead of trait methods to avoid circular dependencies
- All arithmetic operations now working: +, -, *, /, string concat, string repeat
- Add comprehensive arithmetic test file
- Build successful with 0 errors
