Summary

• route close-focused through the explicit session close path when Dispatch Mode has a selected row
• prevents Cmd/Option-W from closing the grid pane focused underneath Dispatch instead of the visible dispatch selection
• keeps normal grid close behavior unchanged outside Dispatch Mode

Root cause

closeFocused() always read activeTab.focusedSessionId. Dispatch Mode keeps its selected row in dispatchMode.focusedSessionId, and that selection can point at a detached agent with no tile-tree leaf. Closing from Dispatch could therefore act on the stale grid focus under the dispatch UI, which looked random to the user.

The existing closeSession(targetId) path already handles explicit-id closes for both detached and grid sessions, so Dispatch close now delegates there.
