/**
 * LI.FI Provider — Cross-chain bridge + swap aggregator
 *
 * Wraps https://li.quest/v1/quote — aggregates ~30 bridges and ~20 DEXes
 * across ~20 EVM chains behind a single API.
 *
 * The quote response carries ready-to-execute calldata: we pass
 * `transactionRequest.to` + `transactionRequest.data` straight into a
 * RelayAdapt multicall. No hardcoded Diamond address — trust the API so
 * we inherit any future contract migrations.
 *
 * Fee model: LI.FI charges a flat 0.25% by default (see `feeCosts`).
 * Integrator fee is 0 unless configured.
