brooklyn! 1ac24fa209 fix(gateway): do not let a launching profile own the host gateway
A profile-scoped parent donated its environ to the host multiplexer, so a
named launcher was treated as the primary adapter owner and its platform
token became the primary claim. Spawn the host with served_profile_child_env
for the default root, mark multiplex active before that primary load, and
name the env-derived side in a duplicate-credential refusal.
