Adds a per-session teardown, distinct from the existing turn-only "stop":
- New WS 'disconnect' message → handleDisconnect → sessionManager.deleteSession,
which fires _claudeKill (kills any in-flight Claude/OpenCode turn) + _sidecarUnsub,
clears the idle timer, and drops the in-memory session. WS stays open so a new
prompt starts fresh. Server acks with 'disconnected'.
- useChat: disconnectSession() + a 'disconnected' handler (commit partial stream,
settle to idle).
- UI: an Unplug button in the chat DetailBar (shown while connected).
Scope note: targets the CURRENTLY-OPEN session (correct in-memory sessionKey).
Disconnecting an arbitrary *listed* session isn't wired yet — session-list rows are
keyed by the on-disk transcript uuid, which isn't the live sessionKey, so that needs
a reverse lookup + a REST endpoint. NOT yet deployed (needs a server restart).
