OtlpHttpProtocol enum

Wire-format protocol for OTLP/HTTP exporters.

The OpenTelemetry specification defines two HTTP encodings:

• application/x-protobuf — protobuf-encoded OTLP messages. The spec-recommended default; smaller payloads, faster to encode.
• application/json — JSON-encoded OTLP messages using the protobuf-to-JSON mapping (proto3 JSON). Optional per spec — SDKs MAY support it — but supported by Dartastic for parity with the JS/Python implementations and for backends that prefer JSON for human-readable telemetry (e.g. local dev UIs, Browser DevTools).

See specification/protocol/exporter.md for the full conformance rules; the env-var OTEL_EXPORTER_OTLP_PROTOCOL (and signal-specific _TRACES_PROTOCOL / _METRICS_PROTOCOL / _LOGS_PROTOCOL variants) selects this from configuration with values http/protobuf or http/json. OtlpHttpProtocol.httpProtobuf is the default.
