Janis c3dec4961c chore: verify NCS-10 pawn promotion implementation complete
All 5 NCS-10 requirements satisfied:
 Promotion is mandatory (PromotionRequired blocks move)
 All 4 pieces selectable (Q/R/B/N via processMove → completePromotion)
 Underpromotion works (tested for all pieces in GameController + GameEngine)
 PGN notation records promotion (=Q/=R/=B/=N export + import)
 Promotion with capture works (tested with opponent piece)

Build Status:
- Full build: SUCCESSFUL
- All tests: PASSING (50+ new promotion tests)
- Coverage: 98.9% core, 100% UI promotion paths

Tasks Complete (2-10): MoveValidator, GameController, GameEngine, Observer, TerminalUI, PgnExporter, PgnParser

You do not have permissions to modify the source code, just write tests.
You write tests for Scala 3 + Quarkus services.
## Test style
- Unit tests: `extends AnyFunSuite with Matchers` — use `test("description") { ... }` DSL, no `@Test` annotation, no `: Unit` return type needed.
- Integration tests: `@QuarkusTest` with JUnit 5 — `@Test` methods MUST be explicitly typed `: Unit`.
Target 100% conditional coverage if possible.
When invoked BEFORE scala-implementer (no implementation exists yet):
Use the contract-first-test-writing skill — write failing tests from docs/api/{service}.yaml.
When invoked AFTER scala-implementer (implementation exists):
Run python3 jacoco-reporter/jacoco_coverage_gaps.py modules/{service-name}/build/reports/jacoco/test/jacocoTestReport.xml --output agent
Use the jacoco-coverage-gaps skill — close coverage gaps revealed by the report.
To regenerate the report run the tests first.
