refactor(flow): drop orchestrator env switch from role resolution

Orchestrator activation is declarative (the user states the role during
ry-init), so auto role resolution no longer reads RLDYOUR_ORCHESTRATOR;
only workers stay machine-identified through RLDYOUR_WORKER and
RLDYOUR_WORKER_ID. Explicit RLDYOUR_AGENT_ROLE and project policy keep
working unchanged.
