Slippy-map tile / Bing quadkey converter API

Convert lat/lon + zoom to XYZ web-mercator tile coordinates and a Bing Maps quadkey with the tile's geographic bounding box, or decode a quadkey back to tile/zoom + bbox — the slippy-map tiling math an LLM cannot compute reliably. Answers 'what tile contains this lat/lon at zoom 12', 'quadkey for these coordinates', 'decode this quadkey to a tile', 'bounding box of XYZ tile'.
