Item ToolTips

Adds a hover tooltip showing an item's name when hovering over its tile in the shop UI - a small, self-contained UI enhancement.

What it actually does

Hooks game:encloseRenderPageFunc (fired once per rendered shop item tile) to attach a floating <div> tooltip element to that tile's canvas, positioned via mousemove, shown/hidden via mousemove/mouseout. Hooks game:clearItemButtons to tear the tooltip and its listeners back down when the shop UI resets (e.g. switching category) - without this cleanup step, tooltips from a previous render pass would silently pile up as detached DOM nodes and stale event listeners every time the shop tiles re-render.

Notes

Purely client-side UI, no server-side behavior at all (only registers client:pluginSourceInsertion). A good minimal reference if you're building something in the same family as Recipe: UI Modification but need it to specifically hook into shop-tile rendering rather than a one-off banner.
