Pause Plugin Execution - Possible?

Nobody has claimed this yet.

xbar 2.17 beta
MacOS 15.3 Sequoia

I have a .sh plugin running each minute, from times to time it needs to take an action that may take more than 1min. So executions are pilling on top of each other. I've added a lock file handling to it like:

```
_lock="${_this_path}/lockfile.${_this}.off"
if [[ -f "${_lock}" ]]; then
exit 0
fi
```

I'm using a 'wait' instruction for the task so it keeps the current run and I can get some output/results out of it:

```
"${_getInstance}" "${_instanceID}" &
_pid=$!
wait $_pid
return 0
```

however, XBar instantiates a new execution whatsoever, obviously. Is there a way to skip an execution if the previous one hasnt finished yet? Or something like it?

The issue names no repository file, test, or entry point; it only describes a Shell plugin and the lock-file and wait snippets used to avoid overlapping runs. Start by locating xbar's plugin scheduling and execution behavior, then determine whether skipped executions are supported and what test or documented behavior would demonstrate completion.
