Consolidate configuration/logging locations

Consolidate configuration & logging locations

Various crates use / hard code $HOME/.config as the location to store various configuration/output files, and using different approaches to resolve $HOME

• using dirs::home_dir()
  • in multiple paces
• resolving $HOME and joining the path
  • in multiple places

We should consolidate on a single approach, and ensure whatever approach we take supports other OSs (windows, etc).

The XDG spec could be something an option to follow: https://specifications.freedesktop.org/basedir-spec/latest/.

We currently put the logs in ~/.config/goose/logs which imo should go somewhere else (maybe $HOME/.local/state/goose?)

I know the mac developer guide recommends things like ~/Library/Application Support (see MOSXAppProgrammingGuide an older guide but seems to still be relevant) , but I do like the ~/.config for MacOS personally, even more from a CLI perspective.

A couple crates we can evaluate:

• https://github.com/dirs-dev/directories-rs
• https://github.com/whitequark/rust-xdg
• https://github.com/cjbassi/platform-dirs-rs
