[Bug]: server status always STOPPED if connected via ssh with ghostty or kitty terminal emulators

[silasjmatson]

User story

As a server manager, I want the details command to show when the server is running so that I am not misinformed

Game

Minecraft

Linux distro

Ubuntu 24.04

Command

command: details

Further information

When connected to a server via ssh on a new terminal emulator (such as ghossty or kitty), calls to tmux will fail with 'unsupported terminal' errors.

These errors are not surfaced by non-interactive scripts, e.g. ./mcserver details, so they result in either silent failures or don't work at all.

./mcserver details on my server shows 0% CPU, 0% Memory, and STOPPED for the server status when the server is actually running. This was because the tmux commands to get this info failed.

I am able to manually resolve by running infocmp -x xterm-kitty | ssh root@myserver -- tic -x - OR by setting TERM=xterm-256color in my ssh config, but that shouldn't be necessary.

mcserver@myserver:~$ echo $TERM
xterm-256color

Steps to reproduce

1. Run a server (e.g a Minecraft server)
2. Run TERM=xterm-kitty ./mcserver details and observe that the status says "STOPPED" even when the server is running
3. Run TERM=xterm-kitty ./mcserver console to see the tmux error
