[FEATURE] Implement Multi-language Comprehensive Documentation and Help System

Is your feature request related to a problem? Please describe.

Users currently lack comprehensive guidance while using the application. While the interface is intuitive, users need more detailed information about resume best practices, feature usage, and common questions. The existing documentation in README.md is primarily focused on development setup rather than user guidance.

Describe the solution you'd like

Implement a complete documentation and help system consisting of:

  1. User Documentation:
  • Create structured documentation using Nuxt Content
  • Include getting started guide
  • Add detailed feature explanations
  • Provide step-by-step tutorials
  • Include keyboard shortcuts and advanced features
  • Support multiple languages through i18n integration
  1. In-App Help:
  • Add help button in main navigation
  • Implement searchable help overlay
  • Create interactive walkthrough for first-time users
  • Add keyboard shortcut reference (?-key overlay)
  • Ensure all help content respects user's language preference
  1. Contextual Help:
  • Add smart tooltips to form fields
  • Implement help icons next to complex features
  • Create hover-activated mini-guides
  • Add example content for each section
  • Translate all contextual help content
  1. FAQ Section:
  • Create searchable FAQ page
  • Include common troubleshooting steps
  • Add export/import guidance
  • Cover ATS optimization tips
  • Maintain language-specific FAQ entries
  1. Resume Guidelines:
  • Add best practices section
  • Include industry-specific tips
  • Provide content writing guidelines
  • Add examples of good/bad content
  • Adapt guidelines for different regions/languages
  1. Language Support:
  • Implement i18n infrastructure for documentation
  • Create translation workflow for content updates
  • Support language switching that matches the main app
  • Ensure proper fallback for untranslated content
  • Maintain consistent terminology across translations

Describe alternatives you've considered

  1. External documentation website only
  2. Video tutorials instead of written documentation
  3. Chat-based help system
  4. AI-powered contextual help
  5. Community-driven wiki system
  6. Separate documentation sites for each language

Additional context

  • Should integrate with existing Nuxt UI components seen in app/components/
  • Documentation needs to follow the project's responsive design principles
  • Help system should be accessible through the existing header navigation in app/components/site/MainHeader.vue
  • Can utilize existing support email infrastructure mentioned in app/error.vue
  • Should maintain consistency with current UI/UX patterns
  • Documentation should be version-controlled alongside the code
  • Translation system should integrate with the main app's i18n infrastructure
  • Consider using language-specific examples and cultural considerations where appropriate
