feat(terminal): show child workflow blocks as nested expandable tree

When a workflow block executes a child workflow, the terminal console
now shows each child block as a nested expandable entry under the
parent — matching the existing loop/parallel subflow pattern.

- Extract childTraceSpans from workflow block output into console entries
- Extend buildEntryTree with recursive workflow node nesting
- Add 'workflow' node type to EntryNodeRow with recursive rendering
- Shared typed utility (extractChildWorkflowEntries) for both execution paths
- Filter UI excludes synthetic child IDs; children follow parent visibility
- CSV export and error notifications skip child workflow entries

  * Renders a single workflow sub-block input based on config.type.

- * @remarks
- * Supports multiple input types including short-input, long-input, dropdown,

- * Handles preview mode, disabled states, and AI wand generation.
- *
  * @param blockId - The parent block identifier
  * @param config - Configuration defining the input type and properties
  * @param isPreview - Whether to render in preview mode
  * @param subBlockValues - Current values of all subblocks
  * @param disabled - Whether the input is disabled
- * @param fieldDiffStatus - Optional diff status for visual indicators
  * @param allowExpandInPreview - Whether to allow expanding in preview mode
- * @returns The rendered sub-block input component
+ * @param canonicalToggle - Metadata and handlers for the basic/advanced mode toggle
+ * @param labelSuffix - Additional content rendered after the label text
+ * @param dependencyContext - Sibling values for dependency resolution in non-preview contexts (e.g. tool-input)
