v0.3.2: add GET /api/artifacts/{id}/raw for content read-back

Metadata (GET /api/artifacts/{id}) stays metadata-only; the full content now
has its own endpoint so an agent can verify exactly what it posted.

- New ArtifactRawView at /api/artifacts/{id}/raw: bearer-or-session auth,
  owner-scoped. Serves exact source text (markdown/html_full/json/csv), file
  bytes (image/pdf/binary), or 404 for render-only kinds (html_fragment/deck).
  Reuses raw_artifact_path/safe_artifact_path.
- serialize_artifact exposes api_raw_url; /api/capabilities advertises the
  route. (The old /a/{id}?raw= viewer stays session-only for browsers.)
- Docs + tests (exact content, owner-scoping, 403 unauth, 404 render-only).
  Suite: 136 passing; verified live.
