Add Russian (Русский) language to localization #206

Feature Request: Add Russian Language Support

Summary

Please add Russian (Русский) as a selectable language option in the application's language/localization panel, alongside the existing English, Deutsch, 한국어, and 中文 options.

Motivation

Adding Russian localization would significantly improve the experience for millions of Russian-speaking users and bring several benefits:

1. Massive User Base

• Russian is spoken by approximately 258 million people worldwide (native + second language)
• It is one of the top 6 most spoken languages globally
• Russia, CIS countries, and Russian-speaking diaspora represent a large and active developer community

2. Growing Open Source Community

• Russian-speaking developers are among the most active contributors to open source projects on GitHub
• Many popular developer tools and frameworks have thriving Russian communities
• Adding Russian support would lower the barrier to entry and encourage contributions from this community

3. Market Expansion

• Russia and CIS countries have a rapidly growing tech ecosystem
• Localized software gains significantly higher adoption in these markets
• Many competing tools already support Russian, making it a baseline expectation

4. Improved Accessibility

• Not all Russian-speaking developers are comfortable navigating English-only interfaces
• Native language support improves comprehension of settings, configurations, and documentation
• Reduces errors caused by misunderstanding UI labels and options

5. Community Goodwill & Contributions

• Open source projects that support multiple languages tend to attract more translators and contributors
• Russian-speaking users often contribute back to localization efforts once the initial framework is in place
• Demonstrates inclusivity and global-mindedness of the project

Proposed Implementation

• Add Русский / Russian as a new option in the language selector dropdown
• Create a new locale file (e.g., ru.json or ru.ts) following the existing i18n pattern
• Translate all UI strings, labels, tooltips, and error messages
• Ensure proper Cyrillic font rendering and text layout

Current Language Options

Currently available: English, Deutsch, 한국어, 中文

Adding Russian would bring the total to 5 supported languages.

Additional Context

• The localization infrastructure already exists and supports multiple languages — extending it to Russian should follow the same pattern
• The Russian-speaking community would likely help maintain and improve translations over time
• This aligns with the project's goal of being accessible to a global audience
