CSV and JSONL — the two formats AI moves data in — step 9 of 9

Last drill. Convert a CSV into JSONL.

Write a function csv_to_jsonl(csv_path, jsonl_path) that:

1. Opens csv_path with csv.DictReader (remember newline="").
2. For each row, converts the score column from string to int.
3. Writes one JSON object per line to jsonl_path.
4. Returns the number of rows written.

The starter writes a tiny CSV, calls your function, then reads the JSONL back and prints each parsed record's name and score.

Expected output:
