Add one-command quickstart: install CLI + skill + launch

New users paste a single curl command. The script:
- Installs Copilot CLI if not present (brew or curl fallback)
- Downloads SKILL.md directly to ~/.copilot/skills/
- Launches copilot with skill pre-loaded (stdin via /dev/tty)

-> ⚡ **Get started fast!** Copy this right into the [Copilot CLI](https://github.com/github/copilot-cli):
-> ```
-> /skills add DUBSOpenHub/havoc-hackathon
+> ### ⚡ One Command. That's It.
+>
+> **Never used the CLI before? No problem.** Follow these 3 steps:
+>
+> **1. Open your terminal**
+> - 🍎 **Mac:** Press `⌘ + Space`, type **Terminal**, hit Enter
+> - 🪟 **Windows:** Press `Win + X`, choose **Terminal** or **PowerShell**
+> - 🐧 **Linux:** Press `Ctrl + Alt + T`
+>
+> **2. Paste this line and press Enter:**
+> ```bash
+> curl -fsSL https://raw.githubusercontent.com/DUBSOpenHub/havoc-hackathon/main/quickstart.sh | bash
 > ```
+> *Already have the CLI? No worries — this detects it and skips straight to adding the skill.*
+>
+> **3. When Copilot opens, type:** `run hackathon`
+>
+> That's it — let the models compete! 🏟️
+>
+> *Requires an active [Copilot subscription](https://github.com/features/copilot/plans). [Get one here →](https://github.com/features/copilot/plans)*
