publisher: themed calendar, NIP-01 nostr adapter, gated brand images

- calendar: one draft per theme/channel (idempotent), rotated schedule
- human gate: approve() audited; AUTONOMOUS_MODE has no effect here by design
- nostr (primary): in-repo NIP-01 client (D4) — canonical serialization,
  sha256 id, BIP-340 schnorr sign via coincurve with zero aux randomness
  (deterministic), pure-python reference verification before publish,
  per-relay publish with isolated errors, event id stored as post_ref
- facebook/instagram adapters: exist but refuse to run unless explicitly
  enabled via env (default deployment never touches Meta)
- images: Pillow brand templates (bh gold / hc orange), 1080x1350,
  template-driven typeset design (not AI-generated media)
- failure isolation: config errors audited, item stays approved

tests: 12 new (event roundtrip+tamper, determinism, key validation,
calendar idempotence, approve gate, nostr happy path, future schedule,
clean config failure, disabled meta adapters, image render) — 41 total

+2. ``approve_draft``: a human approves a specific draft (audited).
+3. ``send_approved``: SMTP sends *only* drafts in state ``approved``.

+Public signatures match the CLI: ``poll()``, ``approve_draft(id, actor)``,
+``send_approved()``. The ``_*`` variants take an explicit session/fetcher for
