A peer invited to an encrypted room needs to find it: the control plane is
pull-based (no server push of invitations), so add a discovery endpoint that
lists every room an endpoint belongs to, with the room's metadata and the
endpoint's role.
- store.ListRoomsForEndpoint: JOIN members+rooms, ordered by room id, empty
slice (not error) for an endpoint in no rooms.
- membershipd: GET /members/{endpoint}/rooms returns {room_id, subject, epoch,
policy, role}[].
- client.ListMyRooms + RoomRef: a bot polls this to discover and then Join +
Subscribe rooms it was invited to.
Tests: store-level (owner in N rooms, member in one, unknown endpoint → []) and
client-level e2e through the embedded harness (B discovers a room A invited it
to, without prior knowledge of the room id; owner sees role=owner).

Chat bots need replies, threads and reactions. Add two optional, omitempty
envelope fields (ThreadID, ReplyTo) plus a REACT frame type. The fields ride the
cleartext envelope (message-id references, not secret content) and are omitted
when unset, so non-threaded frames are byte-for-byte identical on the wire and
their signatures unchanged — a non-breaking, additive change.
Client gains PublishReply (threaded reply) and React (emoji reaction). The
reaction content travels in the payload, so it is sealed like any message and
stays confidential in E2E rooms; receivers dispatch on Frame.Type == REACT and
read Frame.ReplyTo for the target. Publish is refactored to share one
publishFrame path with the new helpers; its behavior is unchanged.
Tests: frame round-trip of a threaded REACT frame (golden), non-threaded
wire/sig back-compat asserting thr/re keys are absent (edge), Unmarshal of
garbage errors (error path), and an end-to-end reply+reaction round-trip in an
encrypted ModeMatrix room.

- membership server returns 403 + human-readable message on missing sealed key (was leaking 'sql: no rows in result set')
- client doJSON unwraps the server's {"error"} field instead of pasting the raw HTTP envelope
