Feat/tournament sort

[GziXnine]

• I have read CONTRIBUTING.md.
• This pull request is all my own work -- I have not plagiarized it.
• All filenames are in PascalCase.
• All functions and variable names follow Java naming conventions.
• All new algorithms have a URL in their comments that points to Wikipedia or other similar explanations.
• All new algorithms include a corresponding test class that validates their functionality.
• All new code is formatted with clang-format -i --style=file path/to/your/file.java.

Summary

Adds Tournament Sort (winner-tree) to the sorts package.

What changed

• Added TournamentSort implementation using a winner tree (stores indices and updates the path to the root after each extraction).
• Added TournamentSortTest integrating with the shared SortingAlgorithmTest suite.

Why this approach

Compared to a naive “rebuild the tree every iteration” or “remove + compact with nulls” approach, this version:

• Keeps extraction at O(log n) by updating only the affected path in the tree.
• Avoids null compaction / repeated scans that can push runtime toward O(n^2).
• Matches repository conventions: no main method, in-place output array (sorts the input array), and includes Javadoc + test.

Closes #6631
