fix: restore user-mode libvirt (no sudo) and fix preseed partitioning

Two critical fixes in this commit:

1. VM Creation Regression (13139f2):
   - Restored qemu:///session (user mode) from qemu:///system (root mode)
   - Changed storage paths from /var/lib/libvirt/images to ~/.local/share/libvirt/images
   - Removed all sudo calls from vm_create and vm_destroy functions
   - Updated test to expect session URI

2. Preseed Partitioning Fix:
   - Added GPT partition table directives
   - Added LVM confirmation settings
   - Fixed EFI partition syntax per Debian official example
   - Fixed /boot max size from 512 to 1024
   - KEY FIX: Added 'partman-auto/choose_recipe select efi-boot-root'

Additional changes:
- Added LICENSE file (GNU AGPL v3.0 only)
- Updated AGENTS.md to enforce auto-commit/push behavior
