Rename Demolish to Deconstruct; add build button grid icons

Browse Source 
Rename the Demolish* terminology to Deconstruct* across the simulation,
events, UI, tests, and docs (DemolishCommand and the DemolishMode* events
become their Deconstruct* equivalents), aligning with the deconstruction
queue at HEAD.

Add per-building SVG icons for the build button grid (REQ-UI-BUILD-GRID):
one color-chip icon per placeable building under data/icons/buildings,
loaded from disk at runtime and rendered with QtSvg onto each build button.
An unaffordable building's button shows a grey-recolored variant via a
QIcon Disabled-mode pixmap (REQ-UI-BUILD-DISABLED). Adds the Qt5::Svg
dependency and deploys Qt5Svg.dll.

A strict separation between the game simulation and the Qt Widgets UI.
- The **simulation** is a pure C++ library that depends only on Qt Core and Qt Gui (QPoint, QVector2D, QRect, etc., as required by the coding guidelines), toml++, and tinyexpr. It contains no QtWidgets, no painting, and no QApplication. Note: in Qt 5, vector math types such as QVector2D live in Qt::Gui rather than Qt::Core, so the lib links both.
- The **UI** reads simulation state and renders it. It owns all widgets, painting, and input handling, and drives the simulation via a small command interface (place building, demolish, clear belt tiles, change recipe, set game speed, etc.).

This split is enforced at the CMake target level (see below). Tests link only against the simulation library and run without a display server.

### UI Events
All UI interactions — building selection, builder/blueprint mode transitions, speed changes, demolish mode, escape menu, layout dialog requests — are communicated via EventManager events rather than Qt signals/slots. Each event is a small struct inheriting `Event` (e.g., `SelectionChangedEvent`, `BuildingTypeSelectedEvent`, `SpeedChangeRequestedEvent`). Widgets register as `CombinedEventHandler` for the events they care about and emit events via `EventManager::sendEventImmediately()`.

Bidirectional interactions use separate request/notification event types to avoid infinite recursion (e.g., `ExitBuilderModeRequestedEvent` from `BuildButtonGrid` → `GameWorldView`, vs. `BuilderModeExitedEvent` from `GameWorldView` → `BuildButtonGrid`).
