Add i18n, tests, and update documentation

Introduces internationalization (i18n) support with English and Turkish, adds unit tests and test setup with Vitest and React Testing Library, and updates documentation including README and changelog. Removes legacy publishing and usage guides, refactors components to use translation system, and updates build and test scripts in package.json. Also adds new utility modules for HLS and CORS, and improves PlayerContext and SettingsMenu for language support.
