0.1.239: fix stationary double-click select not translating

Regression from the click-to-hide feature (#114): dismissTooltipOnClick
sets mouseMoved=false on mouse-down. A stationary double-click never fires
a mouse-move afterward, so mouseMoved stays false and stageTooltipText's
checkWindowFocus() guard (mouseMoved && visible) blocks the selection
tooltip -> no translation. Drag-select worked only because dragging moved
the mouse and set mouseMoved=true.

Fix: in stageTooltipTextSelect, treat a completed (non-empty) selection as
active interaction and set mouseMoved=true before staging. A plain click
makes no selection so the flag stays false and click-to-hide is preserved.

Verified in Chrome with a faithful replica of the gating: before -> BLOCKED,
after -> SHOW (the residual block in automation was only visibilityState
=hidden, which is a background-tab artifact, not present for a real user).

+- 0.1.239
+  - Fix: double-clicking a word in place (or otherwise selecting without moving the mouse) now shows the translation again. The recent click-to-hide behavior reset the "mouse active" flag on mouse-down and a stationary double-click never fired a mouse-move to restore it, so the selection tooltip was suppressed; a completed selection is now treated as active interaction

   - Fix store upload rejection: the Bengali (bn) extension name was 76 characters (store limit is 75); trimmed a redundant conjunction to 74 without changing the meaning
