/**
 * @module plugin/magicblock/pricing
 * @description Per-tool pricing map for the MagicBlock plugin.
 *
 * Two tiers:
 *   - READ  = $0.01/call — read-only queries (ER Router, balances, health, quotes)
 *   - WRITE = $0.05/call — transaction-building + submission (deposits, transfers, swaps, VRF)
 *
 * Prices are expressed in **USDC base units** (6 decimals):
 *   $0.01 = 10_000 micro-USDC
 *   $0.05 = 50_000 micro-USDC
 *
 * The pricing map is consumed by the `PayPerCallHook` to settle
 * SAP escrow or x402 payments after each tool invocation.
