Is your feature request related to a problem?

Currently messages.responsePrefix is applied globally to all outbound replies across all channels. When running multiple channels (e.g., Telegram + WhatsApp), there's no way to apply a prefix to only one channel.

Use case:

With multi-account WhatsApp, when the user messages between their own accounts (e.g., ONE number → TWO number), the bot replies in the same conversation. It becomes confusing who sent which message — the human or the bot. A responsePrefix like [BotName] solves this for WhatsApp, but applying it globally also prefixes Telegram replies where it's unnecessary (since Telegram already shows the bot's name/avatar clearly).

Describe the solution you'd like:

Support per-channel responsePrefix override, e.g.:

{
  channels: {
    whatsapp: {
      responsePrefix: "[Bot] "
    },
    telegram: {
      responsePrefix: ""  // no prefix
    }
  }
}

Or alternatively at the account level for WhatsApp multi-account:

{
  channels: {
    whatsapp: {
      accounts: {
        business: { responsePrefix: "[Bot] " },
        default: { responsePrefix: "[Bot] " }
      }
    }
  }
}

Current workaround:

Using the global messages.responsePrefix which applies to all channels.
