Subject: [PATCH] fix: skip home-based config paths when $HOME is not set

When $HOME is not defined, os.UserHomeDir returns an error. Previously
this caused readFxrc to return an error, which panicked in init().

Instead, skip the home-based paths (~/.fxrc.js and ~/.config/fx/.fxrc.js)
when the home directory is unavailable. XDG_CONFIG_HOME is still honored
if explicitly set.

Fixes #397
