Resolved user home for optional home-based integrations, if available.

Whether the "profile is the home directory" check could not run.

True when the home directory could not be resolved. That silently disables a security check, and this module is imported before any log handler exists, so a log line alone would be invisible even under --debug. dcode doctor reports this field instead.

Abbreviate a path for display.

Paths under the default profile render with a leading ~. A configured profile renders literally, because abbreviating it would hide which profile is in use. A path outside the profile root (an installation path, say) also renders literally.
