fix(honcho): drop unread _client_slot_timeouts bookkeeping

The dict was written on every build and popped/cleared on eviction and
reset, but no read site remained — timeout staleness detection moved
into the cache key itself (a timeout change produces a new identity and
_slot_for evicts the old slot), which the isolation tests already pin.
