Contrato

• assert SpanFromContext returns non-nil noopSpan with invalid span context on nil or empty context
• assert ContextWithRemoteSpanContext produces non-recording span that silently drops SetAttributes and SetStatus
• assert Tracer Start on remote context inherits trace ID and parent span ID for local recording child
• assert WithNewRoot severs remote parent context generating fresh trace ID with zero parent ID
• assert TraceIDFromHex and SpanIDFromHex reject uppercase hex strings and all-zeros per W3C specification
• assert TraceState Insert is immutable, prepends keys to index 0, and rejects uppercase key names
