Add KREW author and remove outdated project cards

[Jwaminju]

What changed

• Registered KREW in _config.yml with the requested name, display name, email, LinkedIn page, and profile image.
• Added the supplied KREW profile image under assets/images/author/KREW.png.
• Replaced the unregistered dailybot author ID with KREW across 20 affected blog posts, including the LeRobot v0.6.0 post.
• Removed the outdated "열린 프로젝트" section from post and sidebar templates, along with its unused styles and JavaScript fallback.

Why

These posts referenced dailybot, which was not present in the site's authors configuration. As a result, their author information was not rendered.

Impact

All affected posts now resolve to the shared KREW author profile and display consistent author information. Outdated project cards are no longer shown below posts or through the sidebar template.

Validation

• Parsed front matter for all 51 posts and confirmed every singular author ID is registered.
• Confirmed all 20 affected posts use author: KREW.
• Confirmed the committed image matches the supplied PNG.
• Confirmed there are no remaining template, style, or script references to the removed section.
• git diff --check passes.
• Full Jekyll build was not run because the local checkout does not have the Jekyll executable installed.
