This change significantly improves the testing infrastructure of the simulation. It adds a suite of new tests for the level generation logic, including unit tests for individual components and a high-level traversability test that validates whether the generated terrain can be navigated by the player.

To achieve this, the LevelGenerator was refactored to separate pure generation logic from Phaser-dependent code, making it fully testable. Several deep-seated bugs in the createFloor function were also identified and fixed, leading to much more robust and reliable terrain generation.

This commit introduces a comprehensive testing suite for the level
generation logic to ensure a higher degree of confidence in future
changes.

Key changes include:
- Added unit and integration tests for the `LevelGeneratorLogic` class,
  covering structure placement and chunk generation.
- Implemented a `TraversabilityValidator` to perform pathfinding on
  generated levels, ensuring the character can navigate them.
- Added a specific test to validate that generated levels are
  traversable from the spawn point to the end.
- Refactored the original `LevelGenerator` to separate the core,
  untestable generation logic from the Phaser-specific rendering code,
  improving modularity and testability.
- Introduced `seedrandom` to make level generation deterministic in
  tests, eliminating flaky tests.
- Fixed several critical bugs in the `createFloor` function that
  prevented it from generating terrain correctly for various chunk
  heights. This ensures the entire width of every chunk is filled with
  terrain.
