/**
 * rpiv-voice — Pi extension. Registers the `/voice` command for local voice
 * dictation backed by sherpa-onnx Whisper.
 *
 * UI 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.
