🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Exercise the affected view hierarchy in the regression test.

These tests call sidebarForegroundNSColor directly with a supplied ColorScheme. They do not render SidebarWorkspaceGroupHeaderView, SidebarMetadataRows, or SidebarMetadataMarkdownBlocks. They also do not configure opposite app and sidebar appearances. A regression that removes the environment dependency or restores .secondary in a consumer would still pass. Add behavior-level coverage through the existing SwiftUI rendering harness.

As per coding guidelines: “When a user reports that tests missed a bug, add behavior-level coverage for the exact reproduction path before claiming the fix is complete.”

In `@cmuxTests/SidebarOrderingTests.swift` around lines 54 - 68, Update the
regression tests around testDarkSidebarUsesWhiteWhenTheAppAppearanceIsLight to
render the affected SwiftUI hierarchy through the existing rendering harness,
covering SidebarWorkspaceGroupHeaderView, SidebarMetadataRows, or
SidebarMetadataMarkdownBlocks with opposite app and sidebar appearance
environments. Assert the rendered foreground colors rather than calling
sidebarForegroundNSColor directly, so consumer-level regressions remain
detectable.
