yiekheng 7af7aa35d0 test(bot): cover the back→re-pair close-leak regression ...

Extract the pair-handler's close-event decision into a pure helper
decidePairListenerOnClose(warmingUp, restartRequired) returning one of
ignore-leaked-close / post-pair-restart / treat-as-timeout. Refactor
pair-handler to call the helper instead of the inline if-chain.

New tests in pair-state.test.ts:
- warmingUp=true → ignore-leaked-close (regression: prior session's
  close racing the new listener)
- warmingUp=true + restartRequired=true → still ignore (defense in
  depth — a stale 515 must not hand control to the reconnect path)
- warmingUp=false + restartRequired=true → post-pair-restart
- warmingUp=false → treat-as-timeout

Bot suite goes from 60 → 64 tests, all green.
