• Included the relevant configuration snippet

• Included a [Minimal, Complete, and Verifiable example] (https://stackoverflow.com/help/mcve)

Version of process-compose: v1.40.1

OS environment:

NixOS unstable

Steps or code to reproduce the issue:

I'd like to use process-compose-flake to generate config files for process-compose. It generates a script which sets PC_CONFIG_FILES environment variable and starts process-compose. While the up operation works as expected, the project update demands that I pass a config file using the --config argument.

cat <<'EOF' > /tmp/test-config.yaml
version: "0.5"

processes:
  hello:
    command: echo 'Hello World'
  pc:
    command: echo 'From Process Compose'
    depends_on:
      hello:
        condition: process_completed
EOF
PC_CONFIG_FILES=/tmp/test-config.yaml process-compose project update

Expected result:

It should run update as instructed using a config set in PC_CONFIG_FILES environment variable.

Actual result:

It complains about missing config file while saying that --config option has default value that I need.
