Ignore *.conf and .env (keeping the committed *.conf.example and
.env.example templates) so runtime credentials stay out of the repo.
Also ignore bridge-vlan-show.txt, tmp/, and downloaded disk images, which
are host-specific dumps and build artifacts rather than source.

Second positional arg is now a codename (bullseye/bookworm/trixie/
forky) mapped to the corresponding cloud.debian.org image, with an
IMAGE_URL env var escape hatch for pointing at something else.
Adds error handling (set -euo pipefail), VM ID/storage validation,
dependency checks, configurable storage/bridge/memory/cores via env
vars, image download caching, and auto-detection of the imported
disk instead of hardcoding filesystem-specific paths.
