/**
 * rpiv-ask-user-question — Pi extension. Registers the `ask_user_question`
 * tool: a structured option selector with an automatically appended
 * `Type something.` custom-answer row.
 *
 * Sentinel labels and TUI chrome strings localize at render time via the i18n
 * bridge. Strings are registered with rpiv-i18n here, once, at module init —
 * but only when the SDK is actually installed. If `@juicesharp/rpiv-i18n` is
 * missing (standalone install of just this package), the dynamic-load shim
 * no-ops and the bridge's `t(key, fallback)` returns the inline English literal
 * at every call site. The extension stays online either way.
 *
 * Adding a locale: drop `locales/<code>.json` next to en.json (mirroring the
 * key set). No edit needed here — `registerLocalesFromDir` iterates
 * `SUPPORTED_LOCALES` from the SDK. See `@juicesharp/rpiv-i18n` README →
 * "Contributing translations" for the full convention.
