Capabilities

- Capabilities
  - `ok` boolean
  - `operation` string
  - `contractVersion` string
  - `apiBaseUrl` string, nullable

  - `trust` object: Facts derived from the running configuration: custody (Swapper holds no funds and never signs), provider (what it receives, what Swapper checks and cannot check), fees, data retention, unknowns.
  - `provider` object: { name: wagyu, apiVersion, unknownOutcomeRecovery }.
  - `statusLongPoll` object: { params: [waitSec, sinceState], maxWaitSec, recheckIntervalSec, note }

  - `funding` object
    - `path` string
    - `url` string, nullable
