After compression exhaustion the auto-reset created a fresh session but
discarded reset_session()'s return value and left the Telegram topic
binding pointing at the oversized compressed child. The next inbound
message in that topic healed the binding forward and switch_session'd the
freshly-reset lane back onto the bloated transcript, re-triggering
compression exhaustion in a loop with a new session id each time.
Capture the fresh entry and re-sync the topic binding to it so the next
message starts clean. No-op on non-topic lanes.
Regression of the #9893/#10063 auto-reset fix.
Fixes#35809
