## 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

The three GameControllerTest bugs described in the entry have been fixed
by the test-writer agent; the file contained no other entries.

- Add BlackKing/WhiteKing to capture board in 'legal capture returns Moved'
so the position is not treated as stalemate after the capture.
- Move WhiteKing from A3 to C3 in three MovedInCheck tests so it no
longer blocks the rook's path along file A.
- Remove Console.withOut(System.out) from withInput so it no longer
overrides the ByteArrayOutputStream installed by captureOutput.

Replace stub branches with GameRules.gameStatus dispatch in processMove
and fill in MovedInCheck/Checkmate/Stalemate cases in gameLoop.
Document 6 pre-existing test bugs in docs/unresolved.md.
