Implements full Windows Hyper-V provisioning

Rewrites setup_env_windows.ps1 to fully implement WINDOWS_PLAN.md with:
- Fixed cloud-init password handling using chpasswd
- Multiple ISO creation fallbacks (oscdimg/WSL/IMAPI2)
- Component skip parameters for VNC, PostgreSQL, Ollama, Playwright
- VNC password support via base64 encoding
- BITS transfer for reliable downloads
- SSH readiness checking before showing connection info

+## [0.13.0] - 2025-01-25
+
+### Changed
+- Rewrote `setup_env_windows.ps1` to fully implement WINDOWS_PLAN.md
+- Password handling uses cloud-init `chpasswd` with plaintext (type: text) instead of broken hash generation
+- Multiple ISO creation methods with fallback chain: oscdimg → WSL genisoimage → IMAPI2 COM
+- Downloads use BITS transfer for reliability with progress reporting
+- SSH readiness checking with timeout before displaying connection info
+
+### Added
+- Component skip parameters: `-SkipVNC`, `-SkipPostgreSQL`, `-SkipOllama`, `-SkipPlaywright`
+- VNC password support via base64 encoding in cloud-init
+- Automatic hosts file cleanup when VM is deleted with `-Force`
+- Proper prerequisite checking for Hyper-V, Windows edition, and admin privileges
+
+### Fixed
+- Cloud-init password configuration (was using bash syntax in PowerShell)
+- ISO creation now works without Windows ADK by using WSL or IMAPI2 fallbacks
+- Hosts file handling with proper admin privilege elevation
+
