Bridge fees are only charged when an operation causes the bridge account
to store an asset long-term. Operations that release assets from existing
escrow or burn assets do not incur a bridge fee.

Reflects changes from onflow/flow-evm-bridge#202

- Add ADR-0001 reference to the fee model callout for full rationale
- EVM-Native EVM→Cadence: note that cross-VM registered NFTs use a
  fee-free handler (handleEVMNativeCrossVMNFTFromEVM); the existing
  steps describe the default path only
- EVM-Native Flow→EVM: note that no fee is charged (NFT is burned,
  no new bridge storage)
