A quick follow-up to 3.3.6 with the small fixes that make the desktop app feel right — the version you're actually running, control over your recent list, and a quit that doesn't flash.

• The "can't click anything" freeze. Confirming a delete (file tree, storage) could leave the whole app unclickable — the modal's focus-return target had just been deleted, wedging an invisible pointer lock. A global safety net now releases it the moment no modal is actually open, across every dialog, drawer, and menu.
• Sending while indexing works. Sending a message during the initial codebase scan errored with "Agent not initialized"; now your message shows immediately with a live status and sends itself the moment indexing finishes.
• Composer hints stop colliding. Squeeze the center column and the keyboard hints now shed their labels, then hide entirely — instead of being clipped under the buttons.
• Tab chips drop the redundant model label when a tab uses the workspace default model.
• About shows the version you're actually running. It reported Electron's version in development builds; it now bakes in the real Empryo version at build time and shows it as a badge next to the title.
• Manage your recent workspaces. The picker now has a per-item remove (hover a row) and a Clear-all — no more permanent list of folders you opened once.
• No flash when you quit. On Linux especially, closing the window briefly flashed the app content before it vanished; the window now hides instantly, so the shutdown animation is the last thing you see.

• The file tree keeps up. When the agent creates a file it now appears in the sidebar automatically, and the tree header gains three buttons — New file, New folder, and a manual Refresh — right beside the hide control.
