/**
 * @module constants/payments
 * @description Payment-token allowlist + agent stake collateral constants
 *   mirroring the on-chain v0.10.0 hardening.
 *
 *   The on-chain program now accepts only:
 *   - **Native SOL** — signalled by `tokenMint = null` on escrow creation.
 *   - **USDC mainnet** — `EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v`.
 *   - **USDC devnet**  — `4zMMC9srt5Ri5X14GAgXhaHii3GnPAEERYPJgZJDncDU`.
 *
 *   Any other SPL mint passed to `createEscrow` / `createEscrowV2` is
 *   rejected on-chain with `PaymentTokenNotAllowed` (error code 6093).
 *
 *   Additionally, the agent owner MUST have an `AgentStake` PDA with
 *   `staked_amount >= MIN_AGENT_STAKE_LAMPORTS` (0.1 SOL) BEFORE any
 *   client can create a new escrow against that agent. Use
 *   {@link StakingModule.initStake} + {@link StakingModule.deposit}
 *   to satisfy the requirement.
