Code Review

This pull request updates the project to Android SDK 37 and Gradle 9.5.1, alongside significant dependency version bumps for AGP, Kotlin, and XR Compose. It refactors spatial space management by moving request logic into the MainActivity and passing callbacks to UI components, while also updating adaptive layout logic to use the new isWidthAtLeastBreakpoint API. Review feedback identifies that the new breakpoint logic (840dp) changes behavior for medium-width devices compared to the previous 600dp threshold and points out that the CompactLayout branches are missing vertical scrolling modifiers required for accessibility on smaller screens.

The CompactLayout branch should include verticalScroll modifiers to ensure content remains accessible on smaller screens, matching the implementation in the ExpandedLayout branch.

                primaryContent = {
                    PrimaryCard(
                        modifier = Modifier.verticalScroll(rememberScrollState())
                    )
                },
                secondaryContent = {
                    SecondaryCardList(
                        modifier = Modifier.verticalScroll(rememberScrollState())
                    )
                }

The breakpoint for switching between CompactLayout and ExpandedLayout has been changed from 600dp to 840dp. This causes Medium-width devices to fallback to the CompactLayout. Consider using WIDTH_DP_MEDIUM_LOWER_BOUND to preserve the original adaptive behavior.

Suggested change

	val isExpanded = windowSizeClass.isWidthAtLeastBreakpoint(
	WindowSizeClass.WIDTH_DP_EXPANDED_LOWER_BOUND
	)
	val isExpanded = windowSizeClass.isWidthAtLeastBreakpoint(
	WindowSizeClass.WIDTH_DP_MEDIUM_LOWER_BOUND
	)
