doJSON, putBlob and getBlob now go through newSignedRequest, which attaches
X-Unibus-Pub/Ts/Nonce/Sig signing membership.CanonicalRequest with the peer's
Ed25519 key. GETs are signed too so the server can authenticate the caller
uniformly under enforce. The payload-level owner signature (invite/rekey)
is unchanged and coexists with this transport-level signature.

Adds the bus-auth rollout (off|soft|enforce) to the control plane. The
middleware verifies an Ed25519 request signature over CanonicalRequest
(method, request-URI, ts, nonce, sha256(body)), checks the timestamp is
within +/-30s, rejects replayed nonces via an in-memory TTL cache (60s), and
requires the signer to be an active user in the allowlist. soft logs
rejections but lets requests through so clients can migrate without an
outage; off is the legacy no-op default. /healthz is exempt so health probes
work before any identity exists. CanonicalRequest is exported as the single
source of truth shared with the client.

Golden: add -> get -> IsAuthorized true, admin seeded. Edge: empty role
defaults to member, case-insensitive hex lookup, list ordering, revoke
denies authorization and stamps revoked_at. Error: duplicate key
(ErrUserExists), invalid role, empty sign_pub, unknown user not authorized,
revoke of unknown/already-revoked. Plus users-table migration idempotency.

Bus-level user allowlist (issue 0001a): the authoritative directory of
Ed25519 signing identities permitted to use the bus, independent of room
membership. Migration is additive and mirrored byte-for-byte between the
module-root migrations/ and the embedded pkg/membership/migrations/.
Store adds AddUser/GetUser/ListUsers/RevokeUser/IsAuthorized/HasAdmin.
IsAuthorized is the single fail-closed predicate both the control plane and
the NATS data plane will consult, so revocation is a status flip that denies
access on both without a restart.

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.

Add a --bind flag (default 127.0.0.1) to membershipd that controls which
network interface both the control-plane HTTP API and the embedded NATS data
plane listen on. Use 0.0.0.0 to expose the stack to the LAN so remote peers
(phones, other PCs) can connect; keep the default for a loopback-only dev stack.
embeddednats gains StartHost(storeDir, host, port) for explicit interface
control; Start stays a backward-compatible wrapper (host "" = nats default
0.0.0.0) so the playground and tests are untouched.

- 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
