mathias 4456d25651 docs: add data model (Stage 0 / Stage 1 scope) ...

Per-user-isolated entities (no global cross-tenant video table per the S5/grill
correction), secrets stored by reference only (ESO/1Password, never the token),
brain delivery modelled as a sink_delivery row rather than brain-specific tables.
fallback_used recorded per summary as the Stage 0 quality signal. Future C dedup
and sharding explicitly out of scope.
