Summary by Sourcery

Release version 2.2.0 with configurable game settings, enhanced assisted mode UX, expanded automated testing, and combined Python/Java coverage reporting.

New Features:

• Allow players to configure colors, code length, and max tries across game modes via shared prompts.
• Support undo operations and display solution elimination percentages in assisted mode.
• Hide human-entered secret codes when setting the secret in applicable game modes.

Bug Fixes:

• Normalize Java test source directory naming in project metadata to use the standard src/test/java layout.

Enhancements:

• Refactor game modes to use shared prompts for settings and secret selection, improving consistency and code reuse.
• Update in-game rules and messaging to reflect variable game parameters and clearer feedback descriptions.
• Promote the package to a stable production release and update project metadata accordingly.

Build:

• Add JaCoCo Maven plugin configuration to generate Java coverage reports.
• Configure pytest paths and Python path in pyproject.toml and add a dev dependency group for test tooling.

CI:

• Add a coverage workflow that runs Python and Java tests, publishes coverage artifacts, and reports to Coveralls and Codacy.
• Adjust the PyPI release workflow to be manually triggered and update the checkout action reference.

Documentation:

• Refresh README badges to highlight testing and coverage status, and tweak contributor documentation to match the current test layout and project status.

Tests:

• Introduce a Python test suite for human, computer, and assisted game modes including feedback parsing, with shared JVM startup for tests and extensive mocking of UI and Java integration.
