feat(core)!: remove `dateDiff` from the core public API

[marcalexiei]

dateDiff is declared in packages/core/src/common/ops.ts

github-stats-extended/packages/core/src/common/ops.ts

Lines 102 to 114 in 31d28cd

	/**
	* Get diff in minutes between two dates.
	*
	* @param d1 First date.
	* @param d2 Second date.
	* @returns Number of minutes between the two dates.
	*/
	const dateDiff = (d1: Date, d2: Date): number => {
	const date1 = new Date(d1);
	const date2 = new Date(d2);
	const diff = date1.getTime() - date2.getTime();
	return Math.round(diff / (1000 * 60));
	};

and re-exported from packages/core/src/index.ts

github-stats-extended/packages/core/src/index.ts

Line 12 in 31d28cd

export { dateDiff, clampValue } from "./common/ops.js";

but nothing inside core calls it.
Its only consumer in the repo is one line in apps/backend/api-renamed/status/pat-info.js:

github-stats-extended/apps/backend/api-renamed/status/pat-info.js

Line 90 in 31d28cd

resetIn: dateDiff(date2, date1) + " minutes",

A five-line date helper should not be part of the published surface of @stats-organization/github-readme-stats-core just to serve one backend call site.
If someone was relying on him, they could inline an equivalent in a minute.

Note

This removes a public export so it should be shipped it as a breaking version bump.
I would consider to ship this alongside a new new major of the action so we can switch to a more standard approach there.
