feat: setup SvelteKit frontend with TypeScript

Implemented issue #9 - Frontend Project Setup with Svelte and TypeScript.

Changes:
- Created SvelteKit project with TypeScript
- Set up routing structure:
  - / (landing page)
  - /login
  - /register
  - /dashboard
  - /bot/[id]
  - /bot/[id]/backtest
  - /bot/[id]/simulate
  - /settings
- Created Svelte stores for state management:
  - userStore - Current user info
  - botsStore - List of user's bots
  - currentBotStore - Selected bot
  - chatStore - Chat messages
  - backtestStore - Backtest results
  - simulationStore - Simulation signals
  - authStore - Authentication state
- Created API client for backend communication
- Set up environment variables (.env.example)
- Created auth store with protected routes and login/register functionality

+
+Everything you need to build a Svelte project, powered by [`sv`](https://github.com/sveltejs/cli).
+
+## Creating a project
+
+If you're seeing this, you've probably already done this step. Congrats!
+
+```sh
+# create a new project
+npx sv create my-app
+```
+
+To recreate this project with the same configuration:
+
+```sh
+# recreate this project
+npx sv@0.15.0 create --template minimal --types ts --no-install .
+```
+
+## Developing
+
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+
+```sh
+npm run dev
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
+```
+
+## Building
+
+To create a production version of your app:
+
+```sh
+npm run build
+```
+
+You can preview the production build with `npm run preview`.
+
+> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.
