Claude 9075fb39b8 feat(quartz): add BOLT12 offer list (NIP-2421 kind 10058)
The NIP was updated to publish a recipient's BOLT12 offer(s) in a dedicated
replaceable event (kind 10058, `bolt12_offer`) instead of a kind:0 field — this
is what ties an offer to a Nostr identity (the author's signature) and gives
BOLT12 zaps the send-side addressability that lightning zaps get from lud16.

- Bolt12OfferListEvent (kind 10058): a BaseReplaceableEvent holding one or more
  `["offer","lno1..."]` tags (reusing OfferTag), with offers()/firstOffer()
  accessors and create/updateOffers factories (mirrors ChatMessageRelayListEvent).
- Registered in EventFactory + a KindNames display entry.
- Tests: offers round-trip + factory typing, malformed-offer-tag filtering, and
  updateOffers replacing the offer set while keeping other tags.

Discovery: a payer fetches the recipient's latest 10058 and picks an offer. The
app-side caching, subscription, editor, and payment intent follow in later commits.
