Subject: [PATCH] fix(ui): SizeDisplay binding must be OneWay (read-only
 property)

LLMSettingsView.xaml bound Run.Text to SizeDisplay with the default
TwoWay mode. SizeDisplay is a read-only computed property (getter only),
so WPF threw XamlParseException at template instantiation time, crashing
the entire LLM provider card list whenever models were present.

Adding Mode=OneWay tells WPF to only read source -> target, which is
valid for read-only properties.
