Please consider using standard XDG paths for configs and data

[bendavis78]

Modern *nix-based applications use the XDG path standard for configuration and data. It used to be that everyone stored things under a dot-dir in the home directory, but this clutters the home directory and doesn't give the user much say in where things are stored. Most *nix systems now have XDG_* environment variables set that specify where apps should store their configuration and data files.

Right now, tabby-agent hard-codes configs AND data under the same folder in the user's home dir.

Instead, tabby should use XDG_* dirs for any paths that write to filesystem to give users the control they expect when using a *nix system.

const xdg = require('@folder/xdg');
const dirs = xdg()

const configFilePath = path.join(dirs.config, "tabby", "config.toml") 
// ~/.config/tabby/config.toml

const dataFile = path.join(dirs.data, "tabby", "agent", "data.json")
// ~/.local/share/tabby/agent/data.json

const logDir = path.join(dirs.data, "tabby", "agent", "logs")
// ~/.local/share/tabby/agent/logs/ 

In my case this is convenient because now I can make my all configurations portable, trusting they will all be in the same place while keeping non-config data such as logs or databases separate.

It's not such a big deal with the server as I can specify the volume mount for the docker server (eg, $XDG_DATA_DIR/tabby or /.local/share/tabby.
