feat(exercises): add JSR-354 workshop exercises (part1–part3)
Introduce hands-on exercises with tests covering: * part1: MoneyExercises, ArithmeticExercises, RoundingExercises, FormattingExercises, ParsingExercises, IntegrationExercises * part2: CurrencyConversionExercises, MonetaryOperatorExercises, MonetaryQueryExercises, MonetaryContextExercises, RoundingStrategyExercises * part3: OrderExercises (end-to-end order workflow) Use incomplete production methods with TODOs and complete JUnit 5 tests (AssertJ only). Tests focus on observable behavior and avoid fragile assertions (e.g., no fixed FX rates). Ensure clear progression from basics to advanced concepts and final integration task.
