Provides lib-side default prop builders for `<ProductReleaseCard>`, covering both the compact `sm` (chat dispatch) and full `lg` (catalog page) card variants without requiring embedder-supplied extras.

## Key Components

### Interfaces

- **`ReleaseLike`** — Minimal shape for `sm` builder; covers image/video thumbnail and date fields
- **`RichReleaseLike`** — Extended shape for `lg` builder; adds `release_type`, `release_status`, `view_count`, `author`, and changelog arrays
- **`DerivedSmProps`** — Output type for the compact builder (`coverImage`, `hasVideoCover`, `formattedDate`)
- **`ProductReleaseCardDerivedProps`** — Full output type for the rich builder, including badge color, author, view count, and changelog counts

### Functions

- **`pickCover(item)`** *(internal)* — Selects the best cover image URL using a simplified sm-specific heuristic: prefers video thumbnails when a video URL is present, otherwise falls back to `featured_image` or `og_image_url`
- **`defaultBuildProductReleaseCardProps(item)`** — Lightweight builder for chat-dispatch `sm` cards; satisfies only the three fields the compact variant reads
- **`buildProductReleaseCardProps(item)`** — Rich `lg`-variant builder and the **default** for `<ProductReleasesView>`; populates the full metadata grid using `resolveReleaseCover` and `releaseTypeToBadgeColor`

## Usage Example

```typescript
import {
  defaultBuildProductReleaseCardProps,
  buildProductReleaseCardProps,
} from './product-release-card-defaults'

// Compact sm card (chat dispatch — no extras needed)
const smProps = defaultBuildProductReleaseCardProps(releaseRow)
// → { coverImage, hasVideoCover, formattedDate }

// Full lg card (ProductReleasesView default)
const lgProps = buildProductReleaseCardProps(releaseRow)
// → { coverImage, hasVideoCover, formattedDate, releaseType,
//     releaseStatus, releaseTypeBadgeColor, viewCount,
//     author, changelogCounts }
```

> Hub-side embedders can override the default by passing a richer builder via `opts.extras.buildProductReleaseCardProps`. The `sm` builder intentionally diverges from `resolveReleaseCover` to avoid pulling hub-only dependencies into the lib bundle.
