v0.28.13 - Move sort() to rows module (2026-03-22)

What Changed?

This release moves sort() from manipulation.ts to rows.ts within the transform/ submodule. The change improves internal organization by grouping row-level operations together. There is no change to the public API — existing code continues to work without modification.

What's New

Main Feature: sort() relocated to rows (transform/)

What it does: sort() is a row-level operation and now lives alongside slice(), head(), and tail() in rows.ts. manipulation.ts now contains only DataFrame lifecycle operations: clone(), copy(), and reset().

How to use it: No changes required. The public API on DataFrame is unchanged.

TypeScript
// Works the same as before
const sorted = df.sort("column", { ascending: true });

Changed
