fix(prompt): increase `EventEmitter`'s max listener count

[devunt]

Description

MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 keypress listeners added to [ReadStream]. Use emitter.setMaxListeners() to increase limit warning when running syncpack prompt. This error makes syncpack prompt practically unusable.

My monorepo contains 11 packages for now, but it will be constantly increasing.

Suggested Solution

Add EventEmitter.setMaxListeners(Infinity) to command entrypoint.

Thanks @devunt, I've never seen this before – if you run syncpack list | nl how many dependencies does it show that you have please?

[devunt]

Not that many. It shows 116 packages are currently used.

[JamieMason]

hm yeah, not many. Thanks, I'll take a look. I'm going away tomorrow until next week though so this might be a while 👍🏻

[JamieMason]

Incase I need it, can you leave your syncpack, OS, and node versions etc?

Since it is a public repository, you may clone it and test it yourself if you need.

[JamieMason]

Thanks, I think this is going to be something basic inside syncpack that affects everyone but we can see.

[JamieMason]

Hi @devunt, please try this with npm install -g syncpack@alpha and reopen this issue if the problem still stands, thanks a lot.
