feat(shipping): meet-at-a-spot suggestions + shipment status (kind 34967)

- HandoffHelper suggests the 3 nearest public skate spots to the listing as
  one-tap DM meetup templates (public data only; never the viewer's location).
- New addressable kind 34967 + useShipmentStatus + ShippingStatusCard: seller
  marks shipped, buyer received, either issue. p-tagged so the push service
  notifies (added to MARKET_KINDS); d=ship:<listing-d>:<author> so a status
  replaces only its author's.
- Honest framing: a self-reported claim, NOT proof - 'received' does not release
  escrow; no address stored; parcel photos with an address discouraged.

+## Shipment Status (kind 34967)

+Optional, **self-reported** logistics for a `ships` deal. Addressable — one slot
+per author:

+```json
+{
+  "kind": 34967,
+  "content": "",
+  "tags": [

+- The **seller** marks `shipped`; the **buyer** marks `received`; either can
+  flag `issue`. Re-publishing the same `d` replaces only that author's status.
+- `p` is the counterparty, so the push service notifies **without decrypting**.
+- ⚠️ It is a **claim, not proof**: `received` does **not** release escrow, and the
+  app verifies nothing here. No address is ever stored — only a coarse status and
