fix(blog): Use relative paths for Jupyter Book links

Update jupyter-book config to generate relative links instead of absolute. This makes the generated site more portable and fixes issues with links on the deployed GitHub Pages site. Also includes the GEMINI.md context file.

+# Gemini Code Context: `const-correctness.github.io`
+
+This document provides context for the AI assistant to understand the structure, conventions, and purpose of this codebase.
+
+## Project Overview
+
+This is a personal website and blog built with React, TypeScript, and Vite. It features interactive 3D elements using `three.js` and `react-three-fiber`, and hosts technical articles written in a Jupyter Book.
+
+- **Frontend**: A single-page application built with React and TypeScript, styled with Material-UI. The main application logic is in `src/App.tsx`.
+- **3D Graphics**: The site includes a 3D model viewer (`src/components/ModelViewer.tsx`) that displays a `.glb` model.
+- **Blog Content**: The technical articles are managed in the `jupyter-books` directory. These are converted to HTML using Jupyter Book and served as part of the React application.
+- **Deployment**: The site is deployed to GitHub Pages via a GitHub Actions workflow defined in `.github/workflows/deploy.yml`.
+
+## Building and Running the Project
+
+The project uses `npm` for package management.
+
+- **Install dependencies**:
+  ```bash
+  npm install
+  ```
+
+- **Run the development server**:
+  Starts the Vite dev server at `http://localhost:5173`.
+  ```bash
+  npm run dev
+  ```
+
+- **Build for production**:
+  This command transpiles the TypeScript and builds the Vite project.
+  ```bash
+  npm run build
+  ```
+
+- **Build and serve the Jupyter Book**:
+  The Jupyter Book content needs to be built and copied to the `public` directory to be accessible by the Vite application.
+  ```bash
+  npm run build:book
+  npm run copy:book
+  ```
+
+- **Linting**:
+  This project uses ESLint for code linting.
+  ```bash
+  npm run lint
+  ```
+
+## Development Conventions
+
+- **Styling**: The project uses Material-UI for UI components. Styling is done via the `sx` prop.
+- **State Management**: Component-level state is managed with React hooks (`useState`).
+- **3D Models**: 3D models are stored in the `public/models` directory.
+- **Blog Posts**: Blog posts are written in Markdown (`.md`) or Jupyter Notebooks (`.ipynb`) in the `jupyter-books` directory. To create a new post, add a file to this directory and update the `_toc.yml` file.
+- **Proxy**: The Vite development server is configured with proxies in `vite.config.ts` to correctly serve the Jupyter Book content.
