Merge main into the voice tilt branch

Re-pin the Realtime tool payload hash for the merged tree (voice geometry plus pitchDeg). To fit main's 55,500 prompt ceiling with Overpass on, the pitchDeg schema drops its -90..90 range (the runner already clamps to -89..-5, now pinned by a test) and its description is shorter. The Overpass prompt measures 55,492.
