Bevy 0.19 — Localization (es-fluent)

When to use this skill

• Adding Fluent-based i18n to a Bevy app (es-fluent-manager-bevy = "0.19.2").
• Defining typed UI messages with #[derive(EsFluent)] and #[derive(BevyFluentText)].
• Wrapping a UI text entity with FluentText<T> for automatic locale-driven refresh.
• Switching locales at runtime via LocaleChangeEvent.
• Reading the current locale from RequestedLanguageId.
