Orbit Pi v0.0.7

Added

• Interface localization via rust-i18n, shipped with ten locales — English, Simplified Chinese, Japanese, Korean, Spanish, French, German, Brazilian Portuguese, Russian, and Italian — plus a System option that follows the OS preferred language. Settings → Appearance → Language switches it live (including the native menu bar); locales/en.yml is the source of truth and scripts/gen_locales.py regenerates the other files from the glossary.
