feat: add cachix push script for pre-building ATM binaries

Browse source

aiolabs.cachix.org so ATMs pull binaries instead of building
from source (which freezes the 2GB RAM hardware).

# Build the douro-installed system closure and push all paths to cachix.
#
# Run from your dev machine (Arch) after pushing code to the repo.
# Requires: nix (Determinate), cachix (authenticated via ~/.config/cachix/cachix.dhall)
#
# Usage:
# ./deploy/push-cache.sh # build + push douro-installed
# ./deploy/push-cache.sh douro # same as above (default)
# ./deploy/push-cache.sh tejo # build + push tejo live config
# ./deploy/push-cache.sh all # build + push all configs
