feat: support pre-setting instance_id via LANGBOT__INSTANCE_ID env var

Browse Source 
In SaaS (cloud edition), the instance_id can now be injected via
environment variable to match the pod UUID. This enables zero-lookup
telemetry routing in Space - no need to reverse-lookup instance_id
to find the pod.
