xno-mcp Purse Custody (Addresses Only)

If xno-mcp is available, treat it as a private wallet custody service:

• The LLM should ask xno-mcp to create a named purse (e.g. "A") and only return addresses.
• Do not ask the user to paste mnemonics/seeds into chat when a purse can be used instead.

Create a purse

Call MCP tool:

• purse_create with { "name": "A", "format": "bip39", "count": 1 }

Expected result shape:

• purse name + format
• A[0] address (nano_...)
