CIDN/CIDL variables do not create functional listeners

[hon1nbo]

Interactsh version:

Client & Server: 1.3.1 (latest according to -up)
Client on MacOs, Server on Debian 13 Trixie

Current Behavior:

CIDL and CIDN create a shorter unique identifier, but no response comes from the listening server for a callback. Behaviour returns to normal with default longer strings.

Expected Behavior:

Callbacks to shorter preambles/nonce combinations should be recorded.

Steps To Reproduce:

1. Run 'interactsh-client --server --token --cidn 3 --cidl 3
2. Obtain a 6 character subdomain for OOB callback
3. Use the OOB callback domain in a known valid injection, or even open in a browser to trigger requests
4. Observe that the interactsh client does not receive or display any notifications of a successful query

Anything else:

I additionally attempted to set CIDN/CIDL on the server to match, and this was not successful either even though it should not be required.
