Family Chat (2.0): a built-in messenger for the family, phase 1

- Chat tab: direct chats and groups, text, attachments, replies, reactions, edit and delete, unread counts, search, drafts, mute and archive
- Live delivery over server-sent events; phone push for people who are not in the app (muted chats stay quiet)
- chat.js keeps conversations and files in data/chat; push.notify sends one person a notification
- Roadmap updated: phase 1 done, combined inbox with Signal still to do

 ## 1. Family Chat (a built-in messenger; text only)
-A messenger inside the hub for the family, so family chats do not need Signal. Every hub account is a contact, and a "Family" group exists from the start. Family chats and Signal chats show in one inbox (labelled by source); people outside the family still use Signal. Messages are kept on the family's own server.

Family chats and Signal chats are meant to show in one inbox (labelled by source; not built yet: for now Chat and Signal are separate tabs); people outside the family still use Signal. Messages are kept on the family's own server.
