Changes

Seed dataset support

Layer / File(s)	Summary
File column parsing web/packages/studio/src/components/SafeSynthesizerFilesetPreview/util.*, web/packages/studio/src/util/files.*	Renames the CSV parser to parseCSVTable and adds column extraction for CSV, JSONL, and JSON array content.
Seed dataset editor web/packages/studio/src/components/ColumnConfigPanel/*	Adds fileset/file selection, content loading, available-column discovery, sampling strategy selection, and seed-specific panel rendering.
Seed dataset graph and config output web/packages/studio/src/routes/DataDesignerJobBuildRoute/columns.*	Adds seed fields, graph tags and deduplicated edges, validation coverage, and seed_config generation while excluding seed columns from regular outputs.
Single seed column palette constraint web/packages/studio/src/components/common/SelectableCard/*, web/packages/studio/src/components/AddColumnPalette/*, web/packages/studio/src/routes/DataDesignerJobBuildRoute/{BuilderPalette.tsx,useJobBuilder.ts,index.tsx}	Propagates disabled reasons to column cards and prevents adding more than one seed-dataset column.

Declare the parser result contract.

parseCSVTable is a public API consumed by getContentColumns; give it a co-located result interface and explicit return type.

In `@web/packages/studio/src/components/ColumnConfigPanel/SeedDatasetConfig.tsx`:
- Around line 125-130: Update the onValueChange handler for the Seed file Select
to clear SEED_AVAILABLE_COLUMNS_KEY whenever the selected file changes, while
still storing the new SEED_FILE_PATH_KEY value. Ensure downstream graph tags and
dependencies cannot reuse columns from the previously selected file during
loading or after a schema error.

In `@web/packages/studio/src/components/common/SelectableCard/index.tsx`:
- Around line 69-84: Update the SelectableCard button to use native
disabled={disabled}, removing disabled cards from keyboard tab order while
preserving the existing click, aria, title, and styling behavior.
