feat: enhance content validation capabilities and improve documentation structure

- Introduced a new validation tool for general content quality, checking for broken links, code syntax, and references.
- Updated the documentation index to improve readability by formatting tutorial and guide links.
- Enhanced the ContentAccuracyValidator to provide detailed confidence metrics and recommendations based on validation results.
- Added helper functions for extracting links and code blocks from markdown files to streamline validation processes.

These changes aim to improve the overall quality and reliability of documentation by ensuring content accuracy and providing actionable feedback during validation.
