Add comprehensive documentation site with MkDocs Material

[firsttris]

This PR adds a complete documentation website for the SendToKodi Kodi add-on, built with MkDocs Material and published to GitHub Pages.

Summary

The documentation was previously scattered across the README and inline comments. This change consolidates it into a structured, searchable website at https://firsttris.github.io/plugin.video.sendtokodi/ with dedicated pages for each topic.

Key changes

• New documentation structure (docs/ directory):

  • installation.md - Installation requirements and setup instructions
  • usage.md - How to send links from browsers, Android, iPhone, and Kodi
  • settings.md - Complete settings reference with descriptions
  • troubleshooting.md - Common issues and solutions
  • faq.md - Frequently asked questions
  • integration.md - JSON-RPC API, plugin URL format, and integration examples
  • how-it-works.md - Architecture and internal flow documentation
  • development.md - Setup, testing, and contribution guidelines
  • README.md - Documentation homepage

• MkDocs configuration (mkdocs.yml):

  • Material theme with custom SendToKodi blue color scheme
  • Navigation structure organized by user type (Users, Integration, Background)
  • Search, syntax highlighting, and git revision date plugins
  • Mobile-friendly responsive design

• Build automation (.github/workflows/docs.yml):

  • Automatic documentation build and deployment to GitHub Pages on master branch
  • Validates documentation builds on pull requests

• Styling (docs/assets/):

  • Custom CSS for SendToKodi branding
  • Icon and favicon assets

• Dependencies (requirements-docs.txt):

  • MkDocs Material 9.7.7
  • Git revision date plugin for automatic last-modified dates

• README.md refactor:

  • Condensed to a focused overview with links to detailed documentation
  • Improved visual hierarchy and feature highlights
  • Links to all documentation pages and integration methods

Notable implementation details

• Documentation uses YAML frontmatter for metadata (descriptions for SEO)
• Mermaid diagrams for architecture visualization
• Admonitions and tabs for better content organization
• All documentation is version-controlled and built from source
• GitHub Pages deployment is automatic on master branch pushes
