Add tenzro namespace (CAIP-2/10/19/25)

[hilarl]

Summary

Adds the tenzro namespace covering Tenzro Network — an L1 settlement layer with HotStuff-2 BFT consensus over a multi-VM execution layer (EVM + SVM + Canton/DAML) sharing a single native balance per asset (Sei-V2-style pointer model).

CAIPs covered

• CAIP-2 — chain ID is the lowercase hex of the first 16 bytes of the genesis block hash (e.g. tenzro:92bd27db9713293097f0e63476e3911e for testnet).
• CAIP-10 — 32-byte addresses, hex (0x + 64 chars) canonical with base58btc accepted on input.
• CAIP-19 — slip44 (native TNZO), token (32-byte token IDs from the unified registry), and nft (32-byte collection ID + token ID). Same identifier resolves to the same balance across all three VM façades.
• CAIP-25 — multi-VM provider authorization, one scope per chain with eth_* / tenzro_* / solana_sign* methods and scopedProperties for vmFacades, dpopBound, evmChainId, nativeAssetCaip19.

Notes

• Mainnet CAIP-2 reference will be added in a follow-up PR at mainnet launch.
• A SLIP-44 coin index PR is being filed in parallel against satoshilabs/slips. Until merged, the slip44 reference uses the pre-registration string tenzro.
