vmix CLI, laptop images, SDL display

CLI (nix run .#):
- `vmix build` and `vmix copy` subcommands
- --image, --generalize key=val, --to-disk, --to-remote-disk
- SDL display auto-detected via DISPLAY temp file passthrough
- --print-build-logs for visible build progress
- -S 4k sparse writes for faster disk copy

Images:
- win10.laptop and win11.laptop bundles (no VirtIO, keeps defender/hibernation)
- templates.bundles.laptop shared template list
- win11 adds reg.disableUCPD on top

Build improvements:
- consistent === vmix: === log prefixes
- SDL display via /tmp/.vmix-display-$$ temp file

Env helpers:
- .env-export-vmix-cli-local: vmix alias for local flake
