 *
 * Two emission shapes (issue #103 Issue 1):
 *
 *   - `'enum'` (DEFAULT): native `export enum X { ... }` — backwards-
 *     compatible with every project that depended on TS enum semantics
 *     (declaration merging via namespace, etc.) before v5.8.34.
 *
 *   - `'const'`: `export const X = {...} as const; export type X = ...` —
 *     compiles under TS 5.5+ `erasableSyntaxOnly` (Vite 7 default).
 *     Call-site ergonomics identical to enum: `X.User === 'user'` works,
 *     string union narrowing works, all helper signatures unchanged.
 *
 * Pass `style` to pick. Default preserves the pre-v5.8.34 behavior so an
 * upgrade without config change doesn't break consumer code.
