Seventh-through-ninth tools in the MCP Apps series. Three Turf.js-based offline polygon-operation tools share a single PolygonOpsAppUIResource that renders the input polygons in muted blue and overlays the result in an operation-keyed color (green=union, purple=intersect, orange=difference). When intersect/difference produces no overlapping geometry, the tool still succeeds (isError=false) and the UI shows just the inputs with a "no overlapping geometry" summary. Also adds the three new offline tools to the annotations test's offlineTools list so the open-world-hint test continues to pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Final resource in the series. Same pattern: send size-changed first, delay 60ms, then map.resize() + fitBounds so polygons fill the viewport instead of appearing as tiny dots. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Final tools in the MCP Apps pattern series. Three offline Turf.js-based polygon-operation tools — `union_app_tool`, `intersect_app_tool`, `difference_app_tool` — share a single `PolygonOpsAppUIResource` (`ui://mapbox/polygon-ops-app/index.html`) that renders the input polygons in muted blue and overlays the result in an operation-keyed color.
Color key
A small bottom-left legend swaps in the right swatch + label per operation.
Graceful no-result
When `intersect` or `difference` produces no overlapping geometry, the tool still returns `isError: false` — the agent gets a "no overlapping geometry" summary, and the UI just shows the input polygons (which makes the empty-result case visually obvious).
Stacked on #194
Final PR in the stack. After everything upstream merges, this will retarget to main.
