Extend grammar system to support base words and punctuation rules:
- gram.word.* for base word translations
- gram.punct.label for language-specific label suffix (FR: " :")
- gram.punct.progress for progress suffix
Label() and Progress() are now language-aware:
- L("status") → EN: "Status:" / FR: "Statut :"
- P("build") → EN: "Building..." / FR: "Construction..."
This enables ~80% reduction in locale file size by composing
phrases at runtime instead of storing every variant.
