Add unit test for StatsManager.reset method

This commit adds a new test file `src/tests/test_stats_manager.py` to verify the functionality of the `StatsManager.reset` method. The test ensures that the `reset` method correctly resets the internal `_displayed` flag, allowing stats to be displayed again after a reset.

Testing:
- Added `test_stats_manager_reset` which mocks the manager and verifies `display_stats` calls before and after reset.
- Verified the test passes in isolation.
- Skipped full integration tests due to environment limitations, but the change is isolated to a new test file and does not modify production code.
