Fix DOMAINSUFFIX being set to echo "Finished"; when running via curl | bash

[Copilot]

When running the install script via curl | bash, the dev setup script's suffix() function reads from stdin to prompt for DOMAINSUFFIX. Since bash is also reading the script from that same stdin pipe, dev setup consumes the remaining unread script bytes — ending up with echo "Finished"; stored as the DOMAINSUFFIX value.

The root cause: DOMAINSUFFIX=.localhost was prefixed to egrep (the first command in the pipeline), not to dev setup. In shell, VAR=value cmd scopes the variable only to that command, so dev setup never received it and fell back to read.

Change

Move DOMAINSUFFIX=.localhost from egrep to dev setup:

# Before
|| DOMAINSUFFIX=.localhost egrep 'php[0-9][0-9]:' "$(DOCKER_COMPOSE_DEVELOPMENT)/docker-compose.yml" \
    | grep -v '-' | sort -ru | awk '{gsub(":","",$1); print $1}' | head -1 \
    | "$(DOCKER_COMPOSE_DEVELOPMENT)/bin/dev" setup

# After
|| egrep 'php[0-9][0-9]:' "$(DOCKER_COMPOSE_DEVELOPMENT)/docker-compose.yml" \
    | grep -v '-' | sort -ru | awk '{gsub(":","",$1); print $1}' | head -1 \
    | DOMAINSUFFIX=.localhost "$(DOCKER_COMPOSE_DEVELOPMENT)/bin/dev" setup

With DOMAINSUFFIX set in its environment, dev setup's suffix() function short-circuits and skips the read, writing DOMAINSUFFIX=.localhost correctly to .env.

@peterjaap  @peterjaap `cat ~/development/.env`

DOMAINSUFFIX=echo "Finished";

DOMAINSUFFIX should be;

DOMAINSUFFIX=.localhost

Something doesnt play nice with https://github.com/JeroenBoersma/docker-compose-development/blob/e83302ea2a040a2030580096e972e9ef68291ab9/bin/dev_command/setup#L85</comment_new>
