Log Message:
wren: restore full-screen drag selection

UIFC handled menu drag selection with its own full-screen copier. The
Wren migration instead routed UI drags through the connected-terminal
selector, whose dimensions are unset before the first connection.

Refactor the selector around explicit screen bounds. Keep a terminal
entry point for connected sessions and route Input.mousedrag() through a full-screen entry point derived from the current conio dimensions. This
also removes the unused scrollback argument and a dead screen buffer.

Set the text-selection pointer when entering the menu, matching UIFC's
mouse initialization, and document the Wren binding's screen scope.
