Detailed Description

VTK ImageData (.vti) I/O for sampled SDF / scalar / vector grid fields.

Writes/reads a GridSdf as an ImageData PointData scalar in ASCII format — human-readable, exact float round-trip, and openable in ParaView. This is the interchange format flow and dem already use for SDF/field grids; consolidating their readers onto this is a follow-up. The reader is tolerant (attribute scan, not a full XML parse) but expects the ASCII inline layout this writer emits; binary/base64 "appended" VTI (what some existing files use) is a noted TODO.
