fix: bypass DM sessions without metadata and make tool globally visible

Browse Source 
1. DM bypass: when neither senderId nor channelId can be extracted from
   the prompt (DM sessions lack untrusted conversation info), skip the
   no-reply gate and allow the message through with end-marker injection.

2. Tool visibility: change whispergateway_tools registration from
   optional=true to optional=false so all agents can see the tool
   without needing explicit tools.allow entries.
