Problem

From Dart MCP review / local analyzer:

1. OS-fragile tooltip test — QueryaStatusBar builds tooltip with Platform.isMacOS ? Cmd+B : Ctrl+B, but querya_status_bar_test.dart always taps Toggle Sidebar (Ctrl+B). Fails on macOS hosts.
2. Analyzer warning — test/features/extensions/extension_workspace_home_test.dart has unused import querya_tab_strip.dart.

Proposal

1. Prefer a stable Key on the sidebar toggle (and assert via key), or branch expected tooltip text on Platform.isMacOS in the test.
2. Remove the unused import; re-run analyzer on the test file.

Files

• lib/features/main_screen/querya_status_bar.dart
• test/features/main_screen/querya_status_bar_test.dart
• test/features/extensions/extension_workspace_home_test.dart

Acceptance

• Sidebar toggle test passes on Linux and macOS
• dart analyze / MCP analyze_files clean on those tests
