Subject: [PATCH] feat: add relay, identity lookup/verify actions (79 total)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New actions per code/core/network/RFC.md:
- blockchain.relay.info — relay network status
- blockchain.identity.lookup — resolve alias to full identity
  (address, type, caps, HNS name, DNS name)
- blockchain.identity.verify — verify address matches alias
  (proof of identity from chain)

Identity resolution follows the 4-layer model:
  wallet → alias → .lthn → DNS

Total Core Actions: 79 (was 73).
