Migrating to v3

v3 removes symbols that were marked @deprecated in v2 and splits the old type category into two focused ones. All replacements have existed since the versions noted below, so upgrading is a find-and-replace exercise — no logic changes required.

@helpers4/type → @helpers4/guard (runtime guards)

Runtime type guards (isString, isArray, isDefined, …) moved to a new @helpers4/guard package. @helpers4/type now only contains compile-time-only utility types (DeepPartial, Maybe, Prettify, …) and has no runtime footprint.

-import { isString, isArray } from '@helpers4/type';
+import { isString, isArray } from '@helpers4/guard';

If you only used compile-time types (import type { DeepPartial } from '@helpers4/type'), no change is needed.

Removed aliases

Removed	Use instead	Available since
object.deepMerge	object.mergeDeep	v1.9.0
object.deepClone	object.cloneDeep	v1.9.0
date.daysDifference	date.difference (richer API: unit, sign)	v2.0.0
date.safeDate	date.ensureDate	v1.9.0
date.dateToISOString	date.toISO8601	v1.9.0
type.isEmpty	array.isEmpty / string.isEmpty / object.isEmpty (per-category)	v2.0.0

Each replacement carries the same JSDoc/behavior as the symbol it replaces.
