restarting officer under a live turn left the browser connected but permanently
silent. the sidecars are pm2 peers, so the agent kept generating and kept
committing to chat_session_events — what died was officer's binding to it. on
`resume-cursor` the server only re-attached the socket when an in-memory session
still existed, so after a restart there was no session and, critically, no
session-scoped subscription relaying sidecar events to the client. the client got
its durable replay and then nothing, which reads exactly like the agent stopping.
adopt the session instead: recreate the record and re-open the subscription
without spawning anything. `_claudeKill` has to be set as part of that — handleChat
treats its absence as "first turn" and would open a second subscription, doubling
every message.
the client now echoes the model and cwd from its session:init back in the
handshake, since after a restart it is the only party that still remembers them.
