Title: ERC7802
Authors: David Dada <daveproxy80@gmail.com> (https://github.com/dadadave80), Modified from ERC-7802 (https://eips.ethereum.org/EIPS/eip-7802)
ERC-7802 crosschain-native ERC-20 extension facet: a trusted bridge (holder of
CROSSCHAIN_BRIDGE_ROLE) mints on the destination chain and burns on the source. Mount
alongside the ERC20 facet; pairs with a BridgeERC7802 that holds the role.
Stateless delegator — logic in ERC7802Lib, balances/roles reuse the ERC20 + AccessControl storage.

- lattice-version: 0.1.0

exportSelectors
ERC-8153 selector export: this facet's cuttable selectors, tightly packed (4 bytes each).
Excludes exportSelectors() itself (0x0ef22643) - it is never cut into a diamond. Order matches
forge inspect ERC7802 methodIdentifiers (alphabetical by signature); kept in exact parity by
ExportSelectorsParityTest. Chunks:
crosschainBurn(address,uint256) 0x2b8c49e3
crosschainMint(address,uint256) 0x18bf5077
function exportSelectors() external pure virtual returns (bytes memory selectors);Returns
