 * Shared utility for resolving ERC-20 token decimals.
 *
 * Used by defi-swap (3 call sites), the plan executor balance resolver,
 * safety-service, and allowance-manager.
 *
 * Strategy:
 * 1. ETH/WETH → 18 (no RPC needed)
 * 2. Well-known stablecoins (USDC, USDT) → 6
 * 3. On-chain `decimals()` call via publicClient
 * 4. Fallback to 18 if all else fails
