* feat(app): unify Explorer tabs and refine interface styling
Give Explorer the workspace tab controls while keeping launcher choices separate from drag-and-drop support.
Upgrade Lucide and set a shared icon stroke width for consistent styling. Reduce the desktop composer bottom inset to align the action row with its corners.
* fix(app): show active Explorer tabs in foreground
The shared row coupled foreground styling to keyboard shortcut ownership. Separate those concerns so Explorer can highlight its active tab while Cmd+T remains with the workspace pane.
* fix(app): refine Explorer close controls and launch options
* test(app): respect singleton Files in Explorer plugin workflow
* test(server): trim unused setup from no-track checkout regression
* test(app): count visible main tab rows after pane moves
* fix(app): prevent and recover workspace layout crash loops
* fix(desktop): capture resized browser tabs without hanging
A resident guest can paint fresh pixels after resize while capturePage's
native surface-copy request remains pending. The same failed guest returns
a fresh frame through frame subscription, so waiting for resize or another
animation frame does not correct the failing copy request.
Capture one subscribed frame within the existing five-second budget and
release the subscription on completion or cancellation. Preserve temporary
frame production and its original throttling policy. Remove viewport copy
retries and E2E screenshot polling; assert the resized image dimensions.
Refs #4866. Three full real-Electron browser journeys passed under Xvfb,
including physical clicks and fresh screenshots while the window is hidden.
* test(app): choose Agent before exercising the runtime catalog
The newly merged catalog journey assumed an empty workspace opened an agent draft tab. This branch opens the New launcher, so create the agent draft tab explicitly before checking its composer and model choices.
* fix: settle closed browser captures and validate persisted layout fixtures
Destroying a guest during frame subscription left its screenshot pending until the capture deadline and blocked queued captures. Reject at destruction, remove the listener on every exit, and return browser_tab_closed. The regression proves immediate settlement and queue release.
Reuse the unchanged persisted layout schema from a UI-independent module so the recovery fixture validates storage before editing it.
* test(app): encapsulate Explorer layout setup and cleanup
Keep persisted layout schemas and corrupted-state construction inside the seedCorruptedWorkspaceLayout helper. Use the existing withWorkspace fixture for cleanup in all four Explorer journeys so test bodies follow a straight setup, action and assertion flow.
* test(app): target the selected workspace in layout recovery
The corruption helper selected the first persisted entry, so a multi-workspace journey could leave the intended workspace untouched. Resolve its exact persistence key from the requested workspace ID and fail setup when absent. The failing-first journey now preserves an earlier workspace with an agent draft tab while recovering the selected workspace.
* feat(app): refine workspace pane actions
Prioritize Changes when available, keep Files useful before a selection, and reserve desktop diff clicks for selection so comments require the explicit affordance. Move the Changes shortcut to Shift+G to avoid consuming a likely copy variant.
* feat(app): improve access to workspace changes
