AssistantMarkdownLink's native branch wrapped its children in a plain RN
<Text>. On iOS that <Text> sits inside the paragraph's native UITextView
and is not hoisted into a UITextViewChild, so link text (markdown links,
bare URLs, and inline-code path links) was silently dropped — the same
root cause as the bold/italic/strikethrough fix in this PR.
Route the native link through MarkdownTextSpan so it composes as a
UITextViewChild and stays visible + selectable. MarkdownTextSpan now
forwards onPress/accessibilityRole across platforms: tappable on
Android/web; on iOS react-native-uitextview nulls onPress on the root
native view, so reliable tap-to-open is still tracked by #21 — but
visible, selectable, copyable link text strictly beats an invisible one.
