🟡 [Medium] wallet list writes human-readable text + JSON to stdout simultaneously (breaks piping)

[askeluv]

Summary

nansen wallet list outputs a human-readable summary followed by a JSON object — both to stdout. Every other command outputs only JSON.

Steps to reproduce

nansen wallet list
# stdout:
#   qa-trader ★
#     EVM:    0x3209...
#     Solana: 6rfZ6B...
#
# {"success":true,"data":{"wallets":[...]}}

Impact

nansen wallet list | jq . errors because of the leading human-readable text. Breaks scripting for any user relying on the wallet list in automation.

Fix

Route human-readable summary to /dev/tty (or stderr), keep only JSON on stdout — consistent with all other commands.
