[review-leftover] #151

• apps/server/src/fork/userMessageTools/SendToUser.ts:409 The refusal for a second main-list message tells the agent to call replace_send_to_user with sub_thread set to the previous message's id, which it finds by reading history back to the main list. However, replace_send_to_user only reads the latest 120 messages via readThreadCores(threadId, false), so after 120 or more messages in other sub-threads, the suggested replacement fails with "none of your messages sent with new_sub_thread has the id".
