Wrap os.homedir() in try/catch and guard against undefined return value
in ThemeManager.getConfigPath(). In CI environments, os.homedir() may be
undefined, causing path.join() to throw and preventing SessionReplay
from being constructed. When homedir is unavailable, theme persistence
is gracefully skipped and the default dark theme is used.
