fix(nip-22): render root event as card using KindRenderer

CRITICAL FIX: Use getCommentRootPointer instead of getCommentReplyPointer
when opening chat on kind 1111 comments.

Previously:
- Clicking "Chat" on a comment-to-comment used getCommentReplyPointer
- This returned the PARENT comment, not the thread ROOT
- Resulted in trying to open chat on intermediate comments
- Failed with "Event not found" when parent wasn't fetchable

Now:
- Uses getCommentRootPointer to find the actual thread root
- Opens chat on the original event (blog post, etc.)
- Properly resolves multi-level comment threads

Also fixes:
- NIP-22 adapter now properly uses getCommentRootPointer in resolveConversation
- Reply detection in eventToMessage uses getCommentReplyPointer correctly
- Reply previews now show for comment-to-comment replies
