  web apps map port 80→local port, enable both tor and tor@default
- Federation: server rename pushes name to peers via background sync
- Server name: fix root-owned file, optimistic store update
- Mesh: local echo for sent messages, sendingArch loading state
- Web5: Message button → Mesh redirect, node name lookup in messages
