Improve large markdown rendering performance

[branyang02]

Summary

• progressively render markdown sections and lazy-load expensive blocks so large notes become interactive sooner
• replace post-render DOM reference rewriting with ReactMarkdown anchor components for equation and blockquote references
• fix underscore equation labels, equation refs inside algorithm/blockquote hover cards, and TikZ/Desmos loader ordering
• add TOC extraction, synthetic benchmarking, and regression tests for renderer, processor, and TikZ behavior

Verification

• npm run format
• npm run lint
• npm test
• npm run benchmark
• npm run build
• git diff --check
• npm pack --dry-run

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secret safely. Learn here the best practices.
3. Revoke and rotate this secret.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
