Add Neurai mainnet addresses to BIP122 namespaces

[NeuraiProject]

Summary

Add Neurai (XNA) mainnet as a test case under the existing bip122 namespace.

Neurai is a UTXO blockchain (Bitcoin / Ravencoin lineage) with its own genesis
block, P2PKH prefix, and SLIP-0044 coin type (1900). It reuses the canonical
bip122 chain-ID definition — no new namespace is needed.

Chain identity

• CAIP-2 Chain ID: bip122:00000044d33c0c0ba019be5c02497304
• Full genesis hash: 00000044d33c0c0ba019be5c0249730424a69cb4c222153322f68c6104484806
• SLIP-0044 coin type: 1900 (registered upstream)
• Mainnet P2PKH prefix: 0x35 (addresses start with N)
• Address format: legacy P2PKH only (no SegWit/bech32 in current consensus)

Genesis hash can be reproduced against the official Neurai node:

neurai-cli getblockhash 0
# 00000044d33c0c0ba019be5c0249730424a69cb4c222153322f68c6104484806​

Notes

• Testnet not included in this PR. Neurai's testnet currently auto-mines
  the genesis block per epoch, so there is no stable testnet reference yet.
  A follow-up PR will add testnet once the protocol freezes a stable genesis.
• Post-quantum keys (ML-DSA-44) are out of scope for this PR. They will be
  proposed separately if/when the broader namespace ecosystem aligns on
  representing post-quantum addresses.
