feat: Clean up repository and add frontend CI

This commit performs a number of cleanup and enhancement tasks on the repository.

Key changes:
- **Python Dependencies:** Moved all Python dependencies to `requirements-dev.txt` and `requirements-docs.txt` and updated the GitHub Actions workflows to use these files.
- **Frontend CI:** Added a new GitHub Action (`frontend-ci.yml`) that triggers on changes to the `frontend` directory. It installs dependencies and runs the linter and build.
- **AGENTS.md:** Created a new `AGENTS.md` file with instructions for AI agents working on the frontend.
- **Documentation:** Updated the root `README.md` and `frontend/README.md` to reflect the new changes. Also fixed typos and inconsistencies in other `README.md` files.
- **Agent Instructions:** Updated `AGENTS.md` and `.github/copilot-instructions.md` to include a new instruction for agents to use the pull request template.

**Note on Testing:**
The frontend testing environment could not be made to work due to a persistent environment issue. The testing setup has been reverted to its original state.

+# Agent Instructions for Frontend Development
+
+This document provides instructions for AI agents working on the frontend of this project.
+
+## Repository Summary
+
+This repository contains a full-stack application with a Python backend and a React frontend. The frontend is built with TypeScript, Vite, and Tailwind CSS.
+
+**Primary Language**: TypeScript
+**Framework**: React (with Vite)
+**Styling**: Tailwind CSS
+**Linting**: ESLint
+**Testing**: Vitest
+
+## Build and Validation Instructions
+
+### Prerequisites
+
+**CRITICAL**: Always run dependency installation before any build or test operations. All commands should be run from the `frontend` directory.
+
+```bash
+# Navigate to the frontend directory
+cd frontend
+
+# Install dependencies
+npm install
+```
+
+### Development
+
+To start the development server, run the following command from the `frontend` directory:
+
+```bash
+npm run dev
+```
+
+### Build
+
+To build the frontend for production, run the following command from the `frontend` directory:
+
+```bash
+npm run build
+```
+
+### Linting
+
+To run the linter, use the following command from the `frontend` directory:
+
+```bash
+npm run lint
+```
+
+### Testing
+
+**CURRENT STATE**: The testing framework (`vitest`) is set up, but the tests are currently not running due to a known environment issue (`uv_cwd` error).
+
+To run the tests (once the environment issue is resolved), use the following command from the `frontend` directory:
+
+```bash
+npm run test
+```
+
+To run the tests with the UI, use the following command:
+
+```bash
+npm run test:ui
+```
+
+## Project Layout and Architecture
+
+The frontend code is located in the `frontend/` directory.
+
+```
+frontend/
+├── src/
+│   ├── components/   → Shared UI components
+│   ├── features/     → Main feature modules
+│   ├── pages/        → Application pages

+├── main.tsx          → Application entry point
+└── ...
+```
+
+## Critical Instructions for Coding Agents
+
+**ALWAYS do the following before making changes:**
+
+1.  **Navigate to the `frontend` directory**: `cd frontend`
+2.  **Install dependencies**: `npm install`
+3.  **Run the linter before committing**: `npm run lint`
+4.  **Follow the component structure**: Place new components in the appropriate feature or components directory.
+5.  **Keep dependencies up to date**: If you add a new dependency, make sure to add it to the `package.json` file.
+6.  **Use the PR template**: When submitting a pull request, please use the provided template.
+
+**NEVER do the following:**
+
+*   Do not commit code that fails the linting checks.
+*   Do not commit code that breaks the build.
+*   Do not add large files to the repository.
+
+**Trust these instructions** - only search for additional information if these instructions are incomplete or found to be incorrect. The testing issue is a known limitation.

 ## Developer Guidance
 
+We have a special set of instructions for AI agents working on this repository. Please review the [AGENTS.md](./AGENTS.md) file for more information.
+
+This repository has a CI/CD pipeline that automatically runs tests and checks for code quality. For the frontend, this includes linting and build checks. For the backend, it includes static analysis and unit tests.
