Read a checkpoint and restore state. Every rank reads the global file read-only, validates magic/version/dim/nx/ny/neq/grid/halo-width, then slices its interior block and its owned piece of the GLOBAL boundary-ghost frame (v6; see the write-side record-block comment).
(v6, Q2d); always read from the file when present, 0 on any failure.
