anti 33f7d5a9ff feat(web): expose attribution state on AttackerDetail backend (Phase 6)
GET /api/v1/attackers/{uuid}/attribution

Returns the merger output for an attacker's identity:

    {
        "identity_uuid": "abc..." | null,
        "primitives": [
            {primitive, current_value, state, confidence,
             observation_count, last_change_ts, last_observation_ts},
            ...
        ]
    }

Pre-attribution-worker: identity_uuid=null, primitives=[]. Surfacing
identity_uuid keeps the cross-attacker rollup story visible to the
frontend ahead of v1's clusterer landing.

api_events SSE relay also subscribes to attribution.> and forwards
to the AttackerDetail page filtered on payload.identity_uuid (the
identity is resolved at stream open from the URL's attacker_uuid;
attribution payloads are identity-keyed, not attacker-keyed). New
SSE event names: attribution.state_changed,
attribution.multi_actor_suspected.

Frontend (AttackerDetail.tsx badge rendering, useAttackerStream
consumer) deferred — there's already WIP on AttackerDetail.tsx in
the working tree; merging the badge logic is a separate commit
once that lands.

Tests: 4 endpoint scenarios — 401 unauth, 404 unknown attacker,
200 empty (no stub), 200 with primitive-ordered rows.

"""GET /api/v1/attackers/{uuid}/attribution — per-primitive
attribution state for one attacker.
Returns the merger output produced by
:mod:`decnet.correlation.attribution_worker` over the observations
linked to this attacker's identity. Pre-clusterer (v0), every
attacker has a 1:1 stub identity, so the returned set is the merger
output for the single attacker; v1's clusterer makes the rollup
cross-attacker.
Empty ``primitives`` is the honest answer when:
- The attribution worker has not yet processed an observation for
this attacker (race with first-sight + behave-shell ingest), OR
- The attacker has fewer than ``MIN_OBSERVATIONS_FOR_STATE``
observations of any primitive — every state row would be ``unknown``,
and the worker writes those, so the empty case is genuinely "engine
hasn't run yet".
The response includes ``identity_uuid`` so AttackerDetail can render
a "rolls up to identity X" hint ahead of the v1 IdentityDetail wire-
up — we don't pretend the keying is per-attacker.
