feat(bluesky): extract external embeds from quoted posts and handle unavailable states

- Extract external link embeds (title, description, thumb) from quoted posts
- Handle blocked quoted posts (#viewBlocked) with "This post is from a blocked account"
- Handle deleted quoted posts (#viewNotFound) with "This post has been deleted"
- Handle detached quoted posts (#viewDetached) with "This post is unavailable"
- Add Detached boolean field for consistency with Blocked/NotFound pattern
- Add logging for JSON unmarshal failures and timestamp parsing errors
- Improve doc comments for embed extraction functions

Also adds beads issue Coves-327 for Phase 3: image/video extraction
