Scoped Message Loading in Vue I18n

[kefahB]

Clear and concise description of the problem

With nested locale files, developers must redundantly write prefixes such as t('homePage.title'), t('homePage.welcome'), etc., inside the HomePage component.

Suggested solution

Add a scope option to useI18n so developers can load a subset of the JSON and avoid redundancy:

const { t } = useI18n({ scope: 'homePage' });
t('title');    // resolves to homePage.title
t('welcome');  // resolves to homePage.welcome

Benefit
Removes repetitive key prefixes, making code cleaner and easier to maintain.
