toward endo-based trading agents: smartWallet plugin can query vstorage, execute offers

[dckc]

This endo plug-in has the essential features of a client in the Smart Wallet Dapp Architecture. It can

• query the chain to look up things like brands and contract instances
• sign and broadcast offers
  • track offers until they complete

The original motivation was the gimix oracle, but
for proof of concept, I started with something simpler: adding collateral to the Inter Protocol reserve:

~/projects/finquick/packages/fincaps$ make reserve-add
++ look up IST in user1 marshal context
endo eval "E(kit.query).lookup('agoricNames', 'brand', 'IST')" -n u1-ist kit:user1-kit
Object [Alleged: IST brand] {}
++ Add to reserve
endo eval "E(reserve).addToReserve(kit.smartWallet, \
  { brand, value: 7_000_000n }, 'add2')" \
  reserve:reserve-tool kit:user1-kit brand:u1-ist
{
  status: {
    id: 'add2',
    invitationSpec: {
      callPipe: [Array],
      instancePath: [Array],
      source: 'agoricContract'
    },
    numWantsSatisfied: 1,
    payouts: { Collateral: [Object] },
    proposal: { give: [Object] },
    result: 'added Collateral to the Reserve'
  },
  tx: {
    height: 270595,
    transactionHash: '4789F93D1BC8262AE8DFB598923BF1267EFED05F287328EC78C888A6EB49EA5C'
  }
}

I got some clues from @kriskowal on how to use the endo cli/daemon, and I learned better ways to do some things that felt awkward. It's starting to feel usable.
