/**
 * Prepares indirect-dispatch arguments by reading `totalPairs[0]` and
 * writing workgroup counts into two slots of the device's
 * `indirectDispatchBuffer` (each slot is 3 × u32 = `(x, y, z)`):
 *
 *   - `sortSlot`: workgroup count for `ComputeRadixSort.sortIndirect`,
 *     computed as `ceil(totalPairs / 2048)` (matches the radix sort's
 *     16×16 thread × 8 elements / thread = 2048 elements/workgroup).
 *   - `boundariesSlot`: workgroup count for `findBoundaries`, computed
 *     as `ceil(totalPairs / 64)`.
 *
 * Slot byte offsets are passed in via two u32 uniforms in a small ad-hoc
 * uniform block (NOT the shared `Uniforms` struct, because the slot
 * indices vary per chunk while the shared uniforms are set per group).
 *
 * @returns WGSL source for the prepare-indirect compute shader.
