rDocs: Suggestion metadata (author, type, text, status) is now persisted
to Automerge alongside comments, surviving page reloads and syncing across
clients. Accept/reject actions record final status (accepted/rejected).
EncryptID: The /join page now has "I'm new" / "I have an account" tabs so
existing users can sign in with their passkey to accept space invites,
instead of being forced to create a duplicate account.
