v0.1.1

First release published to PyPI.

Added

• head / tail accept -n/--lines N (GNU-style) in addition to the positional count.

Fixed

• jlkit head data.jsonl (count omitted) no longer errors with "invalid int value" — a lone positional is treated as the file, not the count.
• jlkit head <non-number> file now exits 2 with a clear message instead of an argparse type error.

Install: pip install jlkit
