Resume conflicts say when the session is open interactively

Resume now tells you when the conversation is already open in another running session.

What

If you try to resume a conversation that another process already holds, Claude Code now checks every holder rather than one, prefers an interactive one, and shows a message naming that case: the conversation is already open in another running Claude session, so use that one or close it. Failures also return an explicit resume_session_live_elsewhere code.

Details
  • The conflict telemetry event gained a holder_kind field.
  • Non-interactive holders still get the generic message.
Evidence

This conversation is already open in another running Claude session \u2014 use that one, or close it and try again

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
