In mini/cli.py, change only the function `cmd_stats` so that it prints a single line `lines=N words=M chars=K` (N, M, K from stats.count_lines, stats.count_words, stats.count_chars of the file) instead of just the lines. Edit only mini/cli.py. Do not edit any other file. Do not run uv, pip or pytest (they are not installed); to check your work use `python3 -m mini.cli stats FILE`. When the edit is done, call done.
