Subject: [PATCH 1/4] fix(7373): native currency is CMX-R, not CMX-U

Chain 7373's native coin is CMX-R, the same coin as its L1. The entry declared
CMX-U, which is not a native coin on any chain: it is issued per project by a
factory contract on 7373. Wallets read nativeCurrency to name the gas asset.

Also marks 7373 as an L2 of eip155-1475 and records EIP1559 support, which the
chain has (baseFeePerGas is present and eth_feeHistory answers).

Subject: [PATCH 2/4] fix(1475): record EIP1559 support

Chain 1475 supports EIP1559. Its base fee is zero by design, which makes it look
like a pre-1559 chain, but baseFeePerGas is present in every block and both
eth_maxPriorityFeePerGas and eth_feeHistory answer.

Subject: [PATCH 3/4] fix: 7373 shortName is cmxr-l2, and restore the trailing
 newline

shortName still read CMX-U, the utility token on the other chain, so chainlist
would have published 7373 under the wrong ticker. cmxr-l2 matches the entry now
merged into ethereum-lists/chains. Also restores the end-of-file newline this
branch had dropped.

Subject: [PATCH 4/4] chainlist: align chain 1475 metadata with ethereum-lists

The canonical entry merged in ethereum-lists/chains uses different values
for four fields. This brings them into line so the two sources agree.

  name           CRYMAD Chain Mainnet Network -> CRYMAD Chain
  nativeCurrency CRYMADX REAL                 -> CryMadX
  shortName      CMX-R                        -> cmxr
  explorer name  crymadchain explorers        -> CRYMAD Chain Explorer

Verify with:
  curl -s https://chainid.network/chains.json | jq '.[] | select(.chainId==1475)'
