Add Windows Hyper-V support for maximum security isolation

Creates setup_env_windows.ps1 PowerShell script that: - Provisions full Hyper-V VMs (not WSL2) for complete isolation - Uses Ubuntu cloud images with cloud-init for automated setup - Generates SSH keys for passwordless access - Adds VMs to hosts file for easy <name>.local access - Disables integration services by default for security Hyper-V provides stronger isolation than WSL2: - Separate kernel per VM - Complete filesystem isolation (no /mnt/c mount) - Own network stack (no firewall bypass) - No ability to launch Windows programs from Linux Also updates README with cross-platform quick start guides and security comparison between WSL2 and Hyper-V.

+
+### Added
+- Windows support via Hyper-V for maximum security isolation
+- `setup_env_windows.ps1` PowerShell script with full VM provisioning
+- Ubuntu cloud image support with cloud-init automation
+- SSH key generation for passwordless VM access on Windows

 ## Project Overview

-This repository contains a dual-mode setup script for creating OrbStack-based development sandboxes tailored for Claude Code with Elixir/Erlang, browser automation, and PostgreSQL.
+This repository provides scripts for creating isolated development sandboxes for Claude Code on macOS (OrbStack) and Windows (Hyper-V). Both platforms offer full VM isolation for safely running AI coding assistants with elevated permissions.
+
+**Supported platforms:**
+- **macOS**: OrbStack VMs (ARM64 Apple Silicon)
+- **Windows**: Hyper-V VMs (maximum security, stronger than WSL2)

+The VM is a real Linux machine with its own filesystem, network, and process space — complete isolation from your host with easy access for development.

+| **Windows** | `setup_env_windows.ps1` (Hyper-V) | Full VM isolation |

 ## Why This Exists

 Running `claude --dangerously-skip-permissions` on your host machine means Claude can execute arbitrary commands, install packages, modify system files, and access everything on your disk. That's powerful for autonomous coding but risky on a machine with your SSH keys, credentials, and personal files.

-This script creates throwaway VMs where Claude can run unrestricted:
+These scripts create throwaway VMs where Claude can run unrestricted:

- **Isolated filesystem** — Claude can't touch your macOS files, keys, or configs
+- **Isolated filesystem** — Claude can't touch your host files, keys, or configs
 - **Isolated network** — services run on their own IP, no port conflicts with your host
- **Disposable** — `orb delete my-sandbox` wipes everything; recreate in one command
+- **Disposable** — delete and recreate in one command
 - **Multiple VMs** — run separate sandboxes per project with shared git credentials

-## Requirements
+### macOS Requirements

 - macOS with Apple Silicon (ARM64)
 - [OrbStack](https://orbstack.dev) installed (`brew install orbstack`)

+## Quick Start (Windows)
+
+```powershell
+# Run as Administrator
+.\setup_env_windows.ps1 -VMName my-project
+
+# Connect via SSH (after provisioning)
+ssh -i $env:USERPROFILE\.ssh\id_ed25519_my-project dev@my-project.local
+
+# Run Claude unrestricted
+claude --dangerously-skip-permissions
+```
+
+If anything goes wrong: `Remove-VM -Name my-project -Force` then run the script again.
+
+### Windows Setup
+
+```powershell
+# Create and provision a VM (run as Administrator)
+.\setup_env_windows.ps1 -VMName my-sandbox
+
+# Customize resources
+.\setup_env_windows.ps1 -VMName my-sandbox -MemoryGB 16 -DiskGB 100 -CPUs 8
+```
+
+On first run, you'll be prompted for:
+- Git commit author name and email (saved to `config.env`)
+- VM user password (not stored, used for initial setup)
+
+### Windows Requirements
+
+- Windows 10/11 Pro, Enterprise, or Education (Hyper-V not available on Home)
+- Hyper-V enabled: `Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All`
+- Windows ADK (for cloud-init ISO creation): [Download](https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install)
+- Administrator privileges
+
+### Why Hyper-V (not WSL2)?
+
+WSL2 is convenient but provides weaker isolation:
+- Shares kernel with all WSL2 instances
+- Host filesystem mounted by default
+- Can launch Windows executables from Linux
+- Network traffic bypasses Windows firewall
+
+Hyper-V provides **maximum security**:
+- Separate kernel per VM
+- Complete filesystem isolation
+- Own network stack
+- No Windows integration by default
+
