Refactor QuantCoder CLI v2.0 - Inspired by Mistral Vibe CLI

Major architectural refactoring with modern Python best practices:

## New Architecture
- Tool-based system inspired by Mistral Vibe CLI
- Modern packaging with pyproject.toml
- Configuration management via TOML files
- Interactive chat interface with prompt-toolkit
- Programmatic mode with --prompt flag
- Rich terminal UI with syntax highlighting

## Core Components
- quantcoder/config.py: Configuration system
- quantcoder/cli.py: Modern CLI with Click + Rich
- quantcoder/chat.py: Interactive & programmatic chat
- quantcoder/core/: LLM handler and article processor
- quantcoder/tools/: Modular tool system

## Tools
- Article tools: search, download, summarize
- Code tools: generate, validate
- File tools: read, write

## Features
- Updated to OpenAI SDK v1.0+
- Conversational AI interface
- Context-aware chat history
- Auto-completion and suggestions
- Syntax-highlighted code display
- Markdown rendering
- Configuration via ~/.quantcoder/config.toml

## Documentation
- README_v2.md: Complete v2.0 documentation
- Updated main README.md
- requirements.txt for easy installation

Breaking change: Requires Python 3.10+

+> **AI-powered CLI for generating QuantConnect trading algorithms from research articles**
 
 QuantCoder is a command-line tool that allows users to generate QuantConnect trading algorithms from research articles using natural language processing and large language models (LLMs). It was initiated in November 2023 and based on a cognitive architecture inspired by the article ["Dual Agent Chatbots and Expert Systems Design"](https://towardsdev.com/dual-agent-chatbots-and-expert-systems-design-25e2cba434e9)
 
 The initial version successfully coded a blended momentum and mean-reversion strategy as described in ["Outperforming the Market (1000% in 10 years)"](https://medium.com/coinmonks/how-to-outperform-the-market-fe151b944c77?sk=7066045abe12d5cf88c7edc80ec2679c), which received over 10,000 impressions on LinkedIn.
 
-As of November 2025, it is under refactoring with readiness expected in February 2026. 
+## 🌟 Version 2.0 - Complete Refactoring

-🧠 LLM Configuration
-By default, this project uses the OpenAI gpt-4o-2024-11-20 model for generating trading code from research articles.
 
-## 💡 Usage
+## 💡 Usage (v2.0)
 
-To launch the CLI tool in interactive mode:
+### Interactive Mode
 
 ```bash
-python -m quantcli.cli interactive
+quantcoder> search "momentum trading strategies"
+quantcoder> download 1
+quantcoder> summarize 1
+quantcoder> generate 1
 ```
 
-Or if `quantcli` is recognized as a command:
+### Direct Commands
 
 ```bash
-quantcli interactive
+quantcoder search "algorithmic trading" --num 5
+quantcoder download 1
+quantcoder summarize 1
+quantcoder generate 1
 ```
 
----
+### Programmatic Mode
 
-## ⚠️ OpenAI SDK Compatibility
+```bash
+quantcoder --prompt "Find articles about mean reversion"
+```
 
-This legacy version uses the **OpenAI SDK v0.28**. Newer versions (`>=1.0.0`) are **not supported**.
+---
 
-If you encounter this error:
+## 📚 Legacy Version (v0.3)
 
-```
-You tried to access openai.ChatCompletion, but this is no longer supported...
-```
-
-Fix it by running:
+For the original version with OpenAI SDK v0.28:
 
 ```bash
-pip install openai==0.28
+git checkout quantcoder-legacy
 ```
 
+See legacy documentation for setup instructions.
