* 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
