Add new setting `dataExplorer.enablePreview` (default: true) that controls whether Data Explorer tabs open in preview mode. When enabled, tabs open with italicized names and are replaced by the next Data Explorer opened, matching VS Code's text file preview behavior. - Add configuration setting and helper function in positronDataExplorerSummary.ts - Update positronDataExplorerService.ts to use setting for runtime data frames - Update positronDataExplorerEditor.contribution.ts for file-based data (CSV, Parquet)

I haven't reviewed this in detail yet, but we'll need to default to false here.
