校验器套装上线:安全校验 bitcoin、monero 与 onion 地址

A mistyped crypto address usually fails loudly. Sometimes it fails silently - checksum-valid but wrong, or subtly malformed in a way that swallows your transaction. The new validator suite catches both kinds before you paste anything anywhere.

What shipped

• the bitcoin validator - legacy, segwit and bech32m formats, checksum verification included
• the monero validator - base58 structure and integrated payment ID detection
• the onion validator - v3 address structure, checksum and version byte
