Pi coding agent: config folder is out of place on Linux

A GitHub issue highlights that the Pi coding agent stores its config in $HOME on Linux, violating the XDG Base Directory Spec. Users request support for XDG_CONFIG_HOME or a fallback to $HOME/.pi. The maintainer acknowledges the issue but resists change due to migration concerns, suggesting PI_CONFIG_DIR as an escape hatch. However, users report that PI_CONFIG_DIR doesn't work as expected, and the discussion reveals a need for clearer configuration options.
