feat(app-shop): local/on-request sales via DM (drop shipping claims)

- Remove the 'Shipped worldwide' and 'At cost, no markup theatre' chips; the
  remaining chips are Lightning, Cashu, Local handover.
- Copy now says sold locally, on request: message me -> we sort the details ->
  pay in sats at handover. No shipping, at all.
- 'How it'll work' -> 'How buying works' (it's a DM, not a cart): Message me /
  We sort it out / Pay in sats.
- New 'Request an item' CTA in the hero that deep-links into a private DM with
  the shop owner (/messages/<PLATFORM_OWNER_PUBKEYS[0] npub>), so a buyer can
  start the conversation with zero checkout machinery.
- Honesty footer states local handover only / no shipping of any kind.
- AGENTS.md documents the model (no cart/checkout/shipping without a decision).
