pub fn default_profile_path() -> Option<PathBuf>Expand description
Returns the default path at which rtcom reads / writes its profile.
Resolves to the platform config directory via XDG / Apple / Known Folder
conventions, e.g. $XDG_CONFIG_HOME/rtcom/default.toml on Linux.
Returns None when no home directory can be determined (unusual — only
hits sandboxed environments without HOME/USERPROFILE).
