/**
 * BlockRun agent-market client — the shared engine behind the `/market`
 * slash command (a human browsing + hiring talent) and the agent_talent
 * tool (the agent hiring talent autonomously, mid-task).
 *
 * The market is business.blockrun.ai: a catalog of paid AI skills, each
 * runnable for ONE standard single-leg `exact` x402 USDC payment on Base.
 * Discovery is a free public GET; running a skill is a paid POST that
 * answers a 402 challenge with a wallet-signed payment — the same dance as
 * the gateway capability in src/tools/blockrun.ts, only the payment header
 * name (`x-payment`) and the base URL differ.
 *
 * Base-only by design: the market settles USDC on Base, so a hire always
 * pays from the EVM wallet (getOrCreateWallet) regardless of the session's
 * configured chain.
