- Measure the trigger's intrinsic size in RN and pin it on the @expo/ui Host;
SDK 55 Host fills available space by default and matchContents reports the
native Menu's size, so neither sized the dropdown correctly.
- Swap ContextMenu (long-press) for Menu (tap-to-open).
- Render native Button/Picker items via the string `label` prop / SwiftUIText
instead of RN <Text> children, which rendered invisibly inside SwiftUI.
- Key/tag Picker options by index to avoid duplicate "[object Object]" keys
from object-valued options (bitrate, media source).
