Adds ChainBitmapRegistry.sol, packing chain support flags for chain IDs 0–255 into a single uint256 storage slot with Yul inline assembly for isChainSupported, setChainSupport, toggleChainSupport, areAllChainsSupported (multi-hop route mask validation), and setBatchChainSupport, plus a custom InvalidChainId revert for out-of-range chain IDs. Adds ChainBitmapRegistry.test.ts covering Yul instruction validation, boundary bit operations, out-of-bounds errors, multi-hop mask checks, and batch updates, with gas benchmarks showing an 80% SLOAD reduction on 5-chain lookups versus standard mapping. Closes MDTechLabs#843
