docs(triage): naming cleanup — ada-3dtiles → 3dgs-tiles (3dgs-* family; ada-* deprecated)

Per user: the crate/DTO family prefix is 3dgs-*, not ada-*. The 3D Tiles
reader (PR #2) is named 3dgs-tiles. Recorded as correction-list #10 so the
plan docs referencing ada-3dtiles (3DGS-Cesium-feature-mapping,
3DGS-3D-Tiles-runtime) get the same rename in Geo's lance-graph lane.
