feat(docs): add interactive demo components for technical appendices

Add placeholder Vue components for visualizing technical concepts across multiple domains including frontend routing, browser rendering, cache design, queue design, database principles, API design, cloud services, and backend evolution. These components provide interactive educational content for the documentation.

Update documentation structure to include new appendix sections and enhance existing content with visual components. Remove unused 'codex' dependency from package.json.
