/**
 * Central XPR transfer cap, enforced at the signing layer.
 *
 * Every signed transaction — core plugin tools (createCliSession) and every bundled
 * or external skill (createCliApi) — passes through assertTransferCap before it is
 * handed to the proton CLI. Individual tools can no longer forget the cap: the
 * total XPR the agent spends in one transaction (eosio.token::transfer, eosio::buyram and
 * eosio::stakexpr)
 * is summed and refused if it exceeds the limit. Account and action names are compared in
 * canonical form, so trailing-dot aliases such as "eosio.token." are counted.
 *
 * Limit, in order of precedence:
 *   1. an explicit `maxTransferAmount` (smallest units, 4 decimals) passed by the caller
 *   2. MAX_TRANSFER_AMOUNT env (smallest units; the documented setting)
 *   3. MAX_TRANSFER_XPR env (whole XPR; legacy name used by skills before 0.8.4)
 *   4. default 10,000,000 = 1,000 XPR
 *
 * Only XPR is capped (the documented cap is denominated in XPR). Other tokens are
 * not limited here.
