[quiquecmtt]

Describe the issue
The hostname plugin doesn't work on MacOS, leaving a @ and a blank space beside the session name.

Steps to reproduce the issue:

1. Install theme through TPM
2. Set @tokyo-night-tmux_show_hostname to 1
3. Reload TMUX config
4. See error

Screenshots
Here you can see the error

Environment (please complete the following information):

• OS: [e.g. Ubuntu 20.04]: MacOS 15.1.1 (24B91)
• terminal [e.g. kitty, alacritty]: GhosTTY 1.0.1
• tmux version [e.g. 3.3a]: 3.5a
• tokyo-night-tmux branch [e.g. master, next, legacy]: master (d610ced)

Additional context
I noticed your script src/hostname-widget.sh utilizes hostnamectl which isn't available on MacOS, may I suggest using the hostname command instead?
This command is already installed in Linux and MacOS by default, and it could be piped to awk so that only the hostname part is shown.

This would be the change needed.

I also tested these commands on a Debian Machine.
