Build & Test (NowChessSystems) TeamCity build finished
feat: implement legal castling (#1)
## Summary

  - Introduces `GameContext` wrapper (board + castling rights) threading through the entire engine pipeline
  - Extends `MoveValidator` with `castlingTargets`, context-aware `legalTargets`/`isLegal` overloads, and helpers (`isCastle`, `castleSide`)
  - Updates `GameRules.legalMoves` and `gameStatus` to use `GameContext`, preventing false stalemate when castling is the only legal move
  - Adds castle detection and atomic execution (`withCastle`) to `GameController.processMove`, plus full rights revocation via source- and
  destination-square tables

  ## Test Plan

  - [ ] 142 tests passing, 100% statement and branch coverage on `modules/core`
  - [ ] White/Black kingside (e1g1/e8g8) and queenside (e1c1/e8c8) castling moves execute correctly
  - [ ] All six legality conditions enforced (rights flags, home squares, empty transit, king not in check, transit/landing squares not attacked)
  - [ ] Rights revoked on king moves, own rook moves, castle moves, and enemy rook captures
  - [ ] False stalemate correctly prevented when castling is the only escape

Unresolved Issues

[2026-03-24] JUnitSuiteLike mixin not available for ScalaTest 3.2.19 with Scala 3

Requirement / Bug: CLAUDE.md prescribes that all unit tests should extend AnyFunSuite with Matchers with JUnitSuiteLike. However, the JUnitSuiteLike trait cannot be resolved in the current build configuration.

Root Cause (if known):

  • ScalaTest 3.2.19 for Scala 3 does not provide JUnitSuiteLike in any public package.
  • The co.helmethair:scalatest-junit-runner:0.1.11 dependency does not expose this trait.
  • There is no org.scalatest:scalatest-junit_3 artifact available for version 3.2.19.
  • The trait may have been removed or changed in the ScalaTest 3.x → Scala 3 migration.

Attempted Fixes:

  1. Tried importing from org.scalatest.junit.JUnitSuiteLike — not found
  2. Tried importing from org.scalatestplus.junit.JUnitSuiteLike — not found
  3. Tried importing from co.helmethair.scalatest.junit.JUnitSuiteLike — not found
  4. Attempted to add org.scalatest:scalatest-junit_3:3.2.19 dependency — artifact does not exist in Maven Central

Suggested Next Step:

  1. Either find the correct ScalaTest artifact/import for Scala 3 JUnit integration, or
  2. Update CLAUDE.md to reflect the actual constraint that unit tests should extend AnyFunSuite with Matchers (without JUnitSuiteLike), or
  3. Investigate whether a different test runner or configuration is needed to achieve JUnit integration with ScalaTest 3 in Scala 3
