Create unified documentation site for commit-check organization

[Copilot]

This PR creates a comprehensive unified documentation site for the commit-check organization that consolidates documentation from both the main commit-check tool and the commit-check-action GitHub Action into a single, professional hub at commit-check.github.io.

Overview

Previously, documentation was scattered across multiple repositories:

• commit-check/commit-check had Sphinx-based docs at commit-check.github.io/commit-check/
• commit-check/commit-check-action only had README-based documentation

This PR establishes commit-check.github.io as the central documentation portal for the entire organization.

What's Added

🏗️ Jekyll Site Infrastructure

• Complete Jekyll-based documentation site with GitHub Pages deployment
• Custom responsive theme with professional navigation
• Automated deployment workflow using GitHub Actions
• SEO optimization with sitemap generation and proper meta tags

📚 Comprehensive Documentation Structure

• Landing Page: Overview of all commit-check tools with quick access links
• Quick Start Guide: Step-by-step setup for GitHub Actions, local development, and Git hooks
• Commit Check Tool Documentation (3 pages):
  • Main documentation with usage examples and configuration
  • Detailed CLI arguments reference
  • Comprehensive configuration guide with examples
• GitHub Action Documentation (2 pages):
  • Complete usage guide with workflow examples
  • Troubleshooting guide for common issues
• 404 Error Page: User-friendly error handling

🎨 Design & User Experience

• Responsive navigation bar with current page highlighting
• Custom CSS styling that matches GitHub's design language
• Code syntax highlighting for all examples
• Cross-referenced links between related tools and features
• Mobile-friendly responsive design

🔄 Content Migration & Enhancement

• Converted existing RestructuredText documentation to Markdown
• Enhanced commit-check tool documentation with additional guides
• Expanded GitHub Action documentation beyond the original README
• Added practical examples and troubleshooting scenarios
• Maintained all existing badges, links, and external references

Key Features

Unified Experience: Users can now access all commit-check documentation from a single, professional site rather than navigating between multiple repositories.

Enhanced Discoverability: The site includes cross-references between tools, helping users discover related features (e.g., linking from CLI tool docs to GitHub Action docs).

Improved Onboarding: The Quick Start guide provides immediate value for new users across all integration methods.

Professional Presentation: Custom styling and navigation create a cohesive brand experience for the commit-check organization.

Technical Implementation

The site uses Jekyll with GitHub Pages for automatic deployment. The structure includes:

• Custom layouts and includes for consistent theming
• SCSS styling for enhanced visual design
• Proper permalink structure for SEO
• Comprehensive GitHub Actions workflow for CI/CD

When merged to main, the site will be automatically deployed to https://commit-check.github.io and serve as the official documentation hub for the commit-check organization.

This addresses the need for a centralized documentation site as requested in the original issue, providing a single source of truth for all commit-check tools and significantly improving the user experience for developers integrating these tools into their workflows.
