Truncate DOT graph node labels to 36 characters using middle-ellipsis to prevent the plan visualization from becoming excessively wide when node names contain long fully-qualified catalog.schema.table paths. The full name remains available in the tooltip (hover) and the side panel details (click). Example: Before: ScanTransformer parquet spark_catalog.longschema.catalog_sales After: ScanTransformer pa…catalog_sales Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

What changes were proposed in this pull request?
Truncate DOT graph node labels to 36 characters using middle-ellipsis when node names are long (e.g., scan nodes with fully-qualified
catalog.schema.tablepaths from custom catalogs).The full name remains available in:
Example:
Why are the changes needed?
When custom catalogs generate long schema/table identifiers, the plan visualization graph becomes excessively wide and hard to read. Most operator labels are under 30 characters; only scan nodes with fully-qualified paths exceed 36 characters.
Does this PR introduce any user-facing change?
Yes. Long node labels in the SQL plan visualization are now truncated with a middle ellipsis. The full name is still accessible via tooltip and side panel.
How was this patch tested?
