 * Adds one built-in block slice to an official workspace project.

 * @param options.blockName Human-entered block name that will be normalized
 * into the generated workspace block slug.
 * @param options.cwd Working directory used to resolve the nearest official
 * workspace. Defaults to `process.cwd()`.
 * @param options.dataStorageMode Optional storage mode for persistence-capable
 * templates.
 * @param options.innerBlocksPreset Optional compound-only InnerBlocks preset
 * (`freeform`, `ordered`, `horizontal`, or `locked-structure`) that controls
 * the generated authoring defaults for nested compound containers.
 * @param options.persistencePolicy Optional persistence policy for
 * persistence-capable templates.
 * @param options.templateId Built-in block family to scaffold. Defaults to
 * `"basic"`.
 * @returns A promise that resolves with the created block slugs, the owning
 * project directory, and the resolved template id after workspace mutation
 * succeeds.
 * @throws {Error} When the template id is unknown, persistence flags are used
 * with unsupported templates, the command runs outside an official workspace,
 * workspace dependencies have not been installed yet, or target block paths
 * already exist.
