Krzysztof kuhy Rudnicki 728d42b230 fix: resolve PERF203 try-except in loop violations
- Extract try-except bodies into helper functions:
  - download_cats: _download_single_image()
  - randomize_numbers: _parse_single_number()
  - lichess_bot/main: _apply_move_to_board(), _process_event_stream(), _run_event_loop_iteration()
- Use else block for return statements after try (TRY300)
- Remove PERF203 from per-file ignores in pyproject.toml
