Laminar OpenTelemetry Trace Ingest API

The standard OpenTelemetry trace ingest endpoint at /v1/traces. Laminar accepts OTLP over gRPC, HTTP+protobuf, and (since May 2026) HTTP+JSON, so any OpenTelemetry-capable runtime — including browser SDKs without a protobuf encoder — can send spans without the Laminar SDK. Authenticated with a project API key; gRPC ingest is served on port 8443 for Laminar Cloud.
