- Add testID="startup-splash" to the simplified splash screen so e2e helpers
can detect desktop daemon bootstrap without depending on removed copy.
- Update startup-dsl helper to assert the testID instead of the deprecated
"Starting local server..." text.
- Replace the obsolete localStorage write for manageBuiltInDaemon in the
local-daemon sidebar test with a get_desktop_settings IPC mock so the
desktop bridge surfaces the seeded host without triggering bootstrap.
