[v0.1.0] — initial release

Extracted from localize_inputs 0.3 alongside localize_datetime_inputs and localize_inputs_core. Carries the number-like form input components — number_input, unit_input, unit_picker — plus their parser, validator, and Ecto Changeset bridge. Does not depend on calendrical; date/time inputs live in localize_datetime_inputs.

Module rename map (from localize_inputs 0.3)

The shared Localize.Inputs.ValidationError and Localize.Inputs.Gettext modules now live in localize_inputs_core.
