fix: move Chromium download to Docker build phase

- Download Chromium from Google snapshots during Docker build (network works there)
- Chroot hook now only verifies and installs runtime dependencies
- Remove generated files from repo (OVMF_VARS.fd, qemu.pid, screenshots)
- Update isotest scripts to use .nogit/ directory structure
- Chromium kiosk verified working with Sway compositor
