v1.3.0

• Atomic file-watching support on Windows, macOS, and Linux using watchdog.

  • Watches parent directories to correctly detect "atomic save" operations.
  • Debounce and file-settle logic prevents false triggers or partial reads.
  • Optional PollingObserver fallback for network, OneDrive, and WSL paths.

• Python version guard (sys.version_info >= 3.10) added at startup to warn users running outdated interpreters.

• Reworked *.py for PEP-8 / pylint compliance:

  • Replaced broad except Exception with specific error classes (OSError, FileNotFoundError, TomlDecodeError, etc.).
  • Reduced class attribute counts to satisfy pylint R0902.
  • Removed unused exercise_keys from _update_list_row_at(self, idx: int, name: str, list_view, exercise_keys)
  • constants.py confroms 100% now as the lambda for EXERCISE_ERROR have been removed and instead ui.py used RED and RESET_LINK.

• Logging initialisation now occurs before any module imports when --debug is used, ensuring early debug output from static methods.

• Background Timer thread exceptions no longer print to stderr or overwrite the Textual TUI.

• Switching between completed exercises no longer produces duplicate or stale watch events.

• Ensured consistent behaviour of --debug flag (logs only active when explicitly enabled).

• General refactor and docstring improvements across watcher.py and theme.py.

• Minor path-handling clean-ups and type hints for maintainability.

• finish messages now is correctly triggered with complete_flag, when update_execise_output and check_all_exercises
