Consider using a signal-like/reactive interface for translations

[macarie]

With a nanostores-like interface:

const { locale, translations, t, useTranslations } = defineTranslationsConfig(...)

locale.listen((locale) => {
    console.log('new locale set:', locale)
})

translations.listen((translations) => {
    valibot.setGlobalMessage((issue) => t(translations.errors.generic, { input: issue.message }))
})

console.log(
    t(
        await (translations.get())
            .article
            .heading
            .publishedBy,
        { ... }
    )
)

const Component = () => {
    const heading = useTranslations(translations, 'article.heading')
    // or like it is now
    const heading = useTranslations('article.heading')

    return <span>{t(heading.publishedBy, { name })}</span>
}

With this interface, it's possible to remove the get* functions and builders, greatly simplifying both the t package and the adapters (~> also allowing the removal of the setup parameter).

This feature would also solve #17.
