Subject: [PATCH] fix: prevent is_repost_then_chat from overriding AI-generated
 comments (#485)

When AI comments are enabled and successfully generated, the
is_repost_then_chat option would overwrite the AI comment with
relay_chat. This fix adds an isAiChat flag so that:
- When AI comment exists: relay_chat is set to the AI comment instead
- When no AI comment: original behavior (chat += relay_chat) is preserved
