Failed sends to a vanished peer now explain why and point you at the peer list.
What's wrong with this entry?
When a send fails because the peer is gone, the error now distinguishes a name-resolved peer from a stale bridge ID and tells you how to find the current peers.
- Name-resolved peers get "that session may have ended, been archived, or disconnected".
- Stale bridge IDs get their own wording.
- A suggestion to call the peer-listing tool is appended only when that tool is present in the current tool set.
— that session may have ended, been archived, or disconnected.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
