splitcheck 0.1.0

First working release.

• check: detect exact and normalized row overlap between two or more splits, with leakage as a fraction of the target split and a CI gate.
• Whole-row or single-column comparison (--on).
• CSV, Parquet, JSON Lines and plain-text input through polars.
• --max-leakage, --json and --no-check to tune gating and output.
