Describe the bug
I think commit 2f90b73 broke the gpclient disconnect command? When attempting to run this command it says the client is already running, which makes sense because we're trying to disconnect.

Expected behavior
After connecting with gpclient connect I believe you should be able to then disconnect using gpclient disconnect. Instead you see the following.

Logs

$ gpclient disconnect
[2025-08-19T05:47:53Z INFO  gpclient::cli] gpclient started: 2.4.5 (2025-07-17)

Error: Another instance of the client is already running

Environment:

• OS: Fedora 42 (x86_64)
• Desktop Environment: GNOME
• Is remote SSH? No
