Thank you Lorna and Jonathan for solving the problem.
Jonathan, I almost always need fontspec options like
[Script=Arabic,Scale=xx,WordSpace=yy] because different nastaliq fonts
seem to have very different letter sizes and word spacing behaviors.
Moreover, for some reason the Noto Nastaliq Urdu font doesn't connect
letters if the Script=Arabic option is omitted.
Noto Nastaliq Urdu is an OpenType font; OpenType requires that the
correct script is specified so that it knows what shaping engine to use.
(There's a default "generic" shaper that is used for Latin & other
simple scripts, so in that case nothing needs to be explicitly
specified, but Arabic and other "complex" scripts require the script to
be specified so that script-specific rules can be applied.)
Awami Nastaliq is a Graphite font; no script option is required as the
shaping behavior is encoded entirely within the font; the engine is
script-independent.
So the Script option is not relevant for Awami, but you do need the
Renderer=Graphite option to use the proper font engine. (The default
word spacing in Awami should generally be quite good, especially if you
use the \XeTeXinterwordspaceshaping=1 setting, but I assume it would
still work to adjust it if you wish.)

The xelatex/fontspec way to say this would be
\newfontfamily\urdufont[Renderer=Graphite]{Awami Nastaliq}
(You might also want to add the option
\XeTeXinterwordspaceshaping=1
to your document, for better word spacing results.)
