/**
 * Normalize full-width characters to their half/full-width canonical form
 * using Unicode NFKC compatibility normalization.
 *
 * Covers in one pass:
 * - Full-width ASCII letters, digits, and symbols (`Ａ-Ｚ`, `ａ-ｚ`, `０-９`, `！-～`) → half-width
 * - Ideographic space (U+3000) → regular space
 * - Half-width katakana (`ｱｲｳ`) → full-width katakana (`アイウ`), including
 *   combining voicing marks (e.g. `ﾊﾟｽﾞﾙ` → `パズル`)
 *
 * Used by SearchBox (opt-in `normalizeFullWidth` prop) and by SelectBox /
 * MultipleSelectBox client-side filter hooks so typing "FPT" matches an
 * option labeled "ＦＰＴ", and typing "ﾊﾟｽﾞﾙ" matches "パズル".
 *
 * Does NOT interconvert hiragana and katakana — callers that need that
 * convention should layer an additional transform on top.
 *
 * @param value - The string to normalize.
