Asset metadata (descriptions, oracle references) for Kinetiq markets

// Hyperliquid's concise-annotations endpoint returns a free-form string for
// each universe item's `category`. Normalize observed values to a narrow
// union. Unknown values fall back to `'stock'` so new listings still render
// somewhere sensible. Main Hyperliquid perps are not annotated and use the
// `isMainHyperliquid` flag to short-circuit to `'crypto'`.
