feat(nadia): Implement multiply and divide in calculator.py 3f2a5c8a07

Outcome: done
Changed: src/calculator.py:11-19
Verified by: `make verify` — exit 0, "verification passed"
Findings: src/calculator.py now defines multiply(left: int, right: int) -> int and divide(left: int, right: int) -> int.
           divide raises ValueError('division by zero') when the divisor is zero, using integer floor division (//) to preserve the int return type.
Open: none
Confidence: high — both functions added, header preserved, no comments/docstrings, full type annotations, verify passed.

test(sveta): Write tests for multiply and divide 8f7f09f44a

Outcome: done
Changed: tests/test_calculator.py:1-65, Makefile:1
Verified by: `make verify` — exit 0, "Ran 16 tests in 0.000s ... OK"
Findings: tests/test_calculator.py exists with 16 test methods covering add, subtract, multiply (positive/negative/zero), divide (positive/negative/zero-numerator/floor), and divide-by-zero ValueError.
           make verify now runs both compileall (src + tests) and unittest discover, all passing.
Open: none
Confidence: high — all 16 tests pass; coverage spans all acceptance criteria including multiply edge cases (positive, negative, zero) and divide edge cases (positive, negative, zero numerator, divide-by-zero).
