UI-launched jobs inherited php-fpm's process group, so stopping one that was
actually running group-killed the WebGUI; setsid makes the job its own group
leader and stop.php now refuses to signal any group it does not lead.
Writing down what each endpoint actually guarantees made the places it
didn't obvious — shell arguments reaching a crontab or a bash -c
unescaped, master.conf written without tmp+rename, and conf edits that
could be saved without ever being parsed.
- Tools and Custom: args input always visible (translucent at rest, full on hover)
- Orch children: args input hidden when orch is on, shown when orch is off
(same toggle as the cron field — orch off = standalone mode)
- vvRunJob/vvDryRun: pick up .vv-script-args value, POST as extra_args
- run.php / dryrun.php: accept extra_args, validate against shell metacharacters,
append to run_job.sh invocation (flows through SCRIPT_ARGS to the script)
- CSS: .vv-script-args — 30% opacity at rest, 100% on hover/focus
