I wanna create the following.
whaddya think?

### The Project Showcase / README

***

# DO (do-cli)
> **The Swiss Army Knife for the Polyglot Developer.**  
> Stop configuring. Stop installing. Just **DO**.

![Version](https://img.shields.io/badge/version-0.1.0-blue) ![Language](https://img.shields.io/badge/language-Python%20%7C%20Rust-orange) ![License](https://img.shields.io/badge/license-MIT-green)

### ❓ What is it?
**DO** is a unified CLI tool designed to handle the entire lifecycle of a "quick script" or a "side project." It automates the friction points of modern development: missing interpreters, messy directories, and repetitive boilerplate.

It detects what you want to do, ensures you have the tools to do it, and cleans up after itself.

### ✨ Key Features

#### 1. Smart Execution (`run`)
Run any file, in any language, without knowing the specific compiler flags.
*   **Auto-Detection:** Sees `.rs`? Runs `rustc`. Sees `.py`? Runs `python3`.
*   **Auto-Installation:** Missing `cargo`? **DO** detects your OS (Arch/Debian/Fedora/MacOS) and offers to install it via your system package manager.
*   **Compilation Cache:** Won't recompile C++/Rust files if the hash hasn't changed.

#### 2. The Sandbox (`sandbox`)
Need to test a library or try a crazy idea? Don't clutter your `~/Documents` folder.
*   Creates a **temporary, isolated environment** in `/tmp/`.
*   Sets up the language stack (Virtualenv, `npm init`, `cargo new`).
*   **Garbage Collection:** Automatically lists and cleans up abandoned sandboxes.

#### 3. Instant Scaffolding (`new`)
Create production-ready directory structures in seconds.
*   Generates a standardized folder structure (Git initialized, `.gitignore` created, entry point file ready).
*   Supports: Python, Rust, Node.js, C++, and Go.

#### 4. The Dashboard (TUI)
A beautiful terminal interface built with **Rich** to manage your active environments.

### 🚀 Usage Demos

#### The "It Just Works" Run
You found an old script. You don't have the runtime.
```bash
$ do run script.rb
[!] Ruby not found.
[?] Detect Arch Linux. Install 'ruby' via pacman? [Y/n] Y
[+] Installing... Done.
[+] Running script.rb...
Hello World!
```

#### The Disposable Sandbox
You want to test a Python library without breaking your main setup.
```bash
$ do sandbox python
[+] Created sandbox "lazy-spinach" (ID: 8f2a)
[+] Path: /tmp/do_sb_8f2a
[+] Virtualenv activated.
[+] Shell spawned. Type 'exit' to leave.

(lazy-spinach) $ pip install requests
(lazy-spinach) $ python main.py
...
```

#### Project Management
See what you are working on.
```bash
$ do list

 ID    | Name           | Type     | Stack  | Status
-------|----------------|----------|--------|------------
 a1b2  | api-gateway    | Project  | Rust   | Active
 9f3c  | lazy-spinach   | Sandbox  | Python | 🕒 Expires 1h
```

#### Cleanup
```bash
$ do rm lazy-spinach
[?] Are you sure you want to delete sandbox 'lazy-spinach'? [Y/n] y
[+] Nuked /tmp/do_sb_8f2a from orbit. 💥
```

---

### 🛠 Architecture

*   **Core Logic:** Python (Porting to Rust in v1.0)
*   **CLI Parser:** `Argparse`
*   **TUI/Formatting:** `Rich`
*   **State Management:** Local JSON Database (`~/.config/do/state.json`)
*   **System Interaction:** `Subprocess` & `Shutil`

### 📦 Installation

```bash
# Clone and Install
git clone https://github.com/UN7X/do-cli.git
cd do-cli
pip install .

# Verify
do --version
```

### 📝 To-Do / Roadmap
- [ ] Add support for Docker-based sandboxes (True isolation).
- [ ] Add "Watch Mode" for hot-reloading compiled languages.
- [ ] Implement `do shell <id>` to re-enter existing sandboxes.
- [ ] Rewrite core runner in Rust for <5ms startup time.
