/**
 * Add one block-to-block transform registration to an existing workspace block.
 *
 * @param options Command options for the block transform scaffold workflow.
 * @param options.cwd Working directory used to resolve the nearest official workspace.
 * Defaults to `process.cwd()`.
 * @param options.fromBlockName Source block name for `--from`. This must be the
 * full `namespace/block` form because transforms may originate from WordPress
 * core or third-party blocks outside the workspace.
 * @param options.toBlockName Target block for `--to`. A workspace block slug is
 * resolved against the workspace namespace, while a full `namespace/block` name
 * must still point at an existing workspace block.
 * @param options.transformName Human-entered transform name that will be
 * normalized and validated before files are written.
 * @returns A promise that resolves with the normalized target `blockSlug`,
 * resolved `fromBlockName`, resolved `toBlockName`, `transformSlug`, and owning
 * `projectDir` after the transform module, transform registry, entrypoint hook,
 * and inventory entry have been written successfully.
 * @throws {Error} When the command is run outside an official workspace, when
 * the target block is unknown, when `--from` is not a full block name, when
 * `--to` uses a non-workspace namespace, when the target block entrypoint does
 * not expose `registration.settings`, when the transform slug is invalid, or
 * when a conflicting file or inventory entry already exists.
