MSWS 1177bfa6bf test: Add JSON test cases and integration tests for chess moves 
```
Add comprehensive test cases for chess scenarios and validate JSON parsing in integration tests

- Add `integration_test.go` to handle JSON test cases, parse data, and validate chess move generation against expected results.
- Add `checkmates.json` with test cases for various checkmate scenarios, including mirrors and edge cases.
- Add `famous.json` detailing positions and test sequences from historical chess games for validation.
- Add `standard.json` to test and verify early-game chess positions and standard move transitions.
- Add `promotions.json` with detailed cases for pawn promotions, including edge scenarios and forced moves.
- Add additional JSON files (`castling.json`, `taxing.json`, `pawns.json`, `stalemates.json`) with test data for specific chess rule validations and edge cases like castling, stalemates, and en passant captures.
```

[testdata/integration_test.go]
- Adds a new test file to validate JSON-defined chess scenarios against board states and expected moves.
- Defines structs for handling test data, including descriptions, starting positions, and expected outcomes.
- Implements a test function to read JSON files in the directory, parse them, and execute tests on the data.
- Introduces helper functions to parse JSON data and iterate through test cases.
- Adds logic to compare expected moves from JSON with generated moves from the chess board state.
- Includes error handling for file reading, JSON unmarshalling, and position validation from the chess board.
[testdata/checkmates.json]
- Added a new JSON file containing test cases for checkmate scenarios.
- Each test case includes a FEN description and an expected output.
  - Descriptions and tests cover specific checkmate types: ladder mate, smothered mate, en passant situations, and minimal-piece mates.
- Added transposed positions for each checkmate scenario to validate mirrored setups.
[testdata/famous.json]
- Added new JSON file containing chess positions and test cases.
- Included a "description" field specifying the context of the chess problems.
- Each test case specifies a starting position (given by a FEN string) and a list of moves along with their corresponding resulting positions (also as FEN strings).
- Added detailed test cases for two famous chess games: "The Game of the Century" and "The Gold Coins Game".
  - For "The Game of the Century", provided multiple legal move sequences and their outcomes from a specific mid-game position.
  - For "The Gold Coins Game", included potential moves and their resulting positions leading to the iconic "Gold Coin move".
- Enriched some moves with descriptive comments for historical or tactical significance.
- Added various chess scenarios to thoroughly test a move generator's capability to handle diverse situations.
[testdata/standard.json]
- Added a new JSON file containing test cases for specific chess board positions.
- The JSON includes:
  - Definitions of starting positions using FEN strings.
  - Descriptions of the starting positions, such as "Standard starting position" and "Ruy Lopez opening".
  - Expected potential moves with resulting FEN states after each move. These moves explore various legal possibilities from the starting positions.
- The file contains test cases primarily for validating early-game configurations and various move transitions in chess.
[testdata/promotions.json]
- Added a new file containing JSON data describing chess test cases focused on pawn promotions.
- Included multiple scenarios covering basic promotion, transposed positions, and edge cases such as forced promotion to escape check or mate.
- Detailed expected moves and resulting board configurations in FEN format for each scenario.
- Descriptions accompanied each test case to clarify the situations being tested, like promoting via capture, forced promotions, or specific checks on the king.
- Covered scenarios where multiple promotion options exist, including promotions resulting in check or checkmate.
[testdata/castling.json]
- Added a new JSON file for castling test cases.
- Created test cases for all possible castling scenarios, including:
  - Normal castling for both sides.
  - Castling when prohibited due to an attacking piece (rook, bishop, knight, queen, king, and pawn).
  - Castling into or through check.
  - Castling when the king or rooks have moved.
- Implemented edge cases, including en passant and pawn-promotion interference with castling rights.
- Included transposed positions to test symmetry and equivalence in board states.
- Supported scenarios where attacks on rooks do not affect castling ability.
- Verified that castling remains allowed despite irrelevant pawn attacks or unoccupied intermediate squares.
[testdata/taxing.json]
- Added a large JSON file containing test cases and expected results for chess positions.
- Introduced different scenarios to analyze edge cases:
  - Positions with pieces in maximal quantity for a specific type (e.g., maximum knights, maximum queens, maximum bishops).
  - Transposed positions to verify symmetric behavior.
  - Special rules scenarios like prohibited en passant captures due to check.
- Organized data with a `description` for each scenario, `start` positions in FEN format, and corresponding `expected` moves with their resulting positions.
- Ensured diverse test coverage, including:
  - Positions designed to stress test move generation.
  - Positions covering intricate rules interactions like pawn structure scenarios (en passant).
  - Positions with multiple complexity levels (low-mobility vs high-mobility positions).
[testdata/pawns.json]
- Added a new JSON file defining test cases involving pawn positions in chess.
- The test cases cover various scenarios with en passant possibilities, moves without en passant, and full pawn setups.
- Each test scenario details the starting board position (FEN), a description, and expected moves along with the resulting FEN after each move.
- Includes mirrored or transposed versions of positions to test symmetry and edge cases.
- Scenarios test both legal and illegal moves, focusing on edge cases like restricted en passant and pawn movement logic.
- Ensures test coverage for complex pawn interactions, including rows with dense pawn positions and potential captures.
- Scenarios also evaluate king movements in relation to pawns.
- Emphasizes positions where rule-specific mechanics, like en passant, are critical to validate correctness.
[testdata/stalemates.json]
- Added a new JSON test data file for stalemate cases in chess.
- Included multiple test cases with starting positions (FEN notation) and expected results.
- Each test case represents a specific stalemate scenario or its transpose (mirrored version).
- Some descriptions provide details about positions, such as the shortest stalemate possible.
- Empty arrays are used for expected outputs, implying no further data is expected from these stalemate setups.
