Listing other Claude sessions now explains an empty result instead of a bare line.
What's wrong with this entry?
Listing other Claude sessions on the machine no longer just prints "No reachable agents.". It names your own session first and distinguishes "no other Claude session is running on this machine right now" from "no other session appears in this listing right now", noting in both cases that sending messages between sessions still works.
- Failures are now reported separately for the three ways the listing can come up short: walking the connection between sessions, building the local list, and messaging being turned off.
- Unconditional, no flag.
peer messaging itself is available; a session appears here once it is started
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
