Introduce optional httpx-based HTTP/2 transport behind OTEL_EXPORTER_OTLP_HTTP_TRANSPORT=httpx, add exponential backoff with jitter for 429/5xx honoring Retry-After, and gracefully fall back to HTTP/1.1 when HTTP/2 negotiation fails. Includes unit tests for transport selection and Retry-After parsing. Backwards compatible (requests remains default).
