Adds an “aquarium” animation overlay to the Agents window new-session screen, with a persistent toggle button in the chat bar and animated VS Code-logo “fish”/food interactions.

Changes:

• Implements animated fish/food/water layers and supporting SVG generation + styling.
• Adds supporting context key, i18n resource mapping, and stylelint allowlisting for new CSS variables.

• Food drops are wired to EventType.MOUSE_DOWN. On iOS this event doesn’t fire (pointer events are used), so users won’t be able to drop food. Please use addDisposableGenericMouseDownListener (or pointer events) for cross-platform input.

	store.add(addDisposableListener(mainContainer, EventType.MOUSE_DOWN, (e: MouseEvent) => {
		// Only spawn food on plain left clicks against background-ish surfaces.
		if (e.button !== 0) {
			return;
		}
