otlp_stream_transport

/**
 * Create a stream transport for OTLP that writes JSONL to a single destination.
 *
 * Accepts an absolute file path or a php:// stream wrapper such as
 * 'php://stdout', 'php://stderr', 'php://memory', or 'php://temp'. Each
 * export() call appends one JSON Line under LOCK_EX so concurrent writers
 * interleave at line boundaries. The $filePermissions and $createDirectories
 * parameters apply only when the destination is a file path.
 *
 * Per the OTLP File Exporter spec only JSON encoding is supported.
