fix(mermaid): fix mermaid charts.

[rubixvi]

This pull request primarily updates the Mermaid diagram rendering component to improve reliability and diagram normalization, and upgrades several dependencies for improved stability and compatibility. It also standardizes import paths for the Link component and updates related documentation examples.

Mermaid diagram rendering improvements:

• Refactored the Mermaid component in components/markdown/mermaid.tsx to use memo, simplify rendering logic, and normalize chart input for more consistent diagram rendering. Added error handling and updated Mermaid initialization with startOnLoad: false and securityLevel: 'loose'.
• Updated documentation in contents/docs/markdown/diagrams/index.mdx to use the new, simplified Mermaid usage pattern and improved chart formatting for clarity and consistency. [1] [2] [3]

Dependency and tooling upgrades:

• Upgraded mermaid to 11.14.0, next to 16.2.3, react and react-dom to 19.2.5, and several other dependencies and devDependencies for improved stability and compatibility. [1] [2]
• Updated biome.json schema and @biomejs/biome version for the latest linting and formatting support. [1] [2]

Codebase consistency:

• Standardized the import path for the Link component to always use @/lib/transition across app/not-found.tsx, app/page.tsx, and components/anchor.tsx. [1] [2] [3]
