fix(loop-detection): clear the per-tool frequency counter on evict/reset (#4295) ...

`_evict_if_needed` and `reset` dropped `_tool_name_history` (the windowed
deque) but left `_tool_name_counter` (the Counter that mirrors it) in place.
After a thread id was LRU-evicted and later reused, its frequency count
resumed from the stale value instead of zero, so the first fresh tool call
was force-stopped ("Tool X called N times") as if the evicted calls had
never rotated out. `reset()` had the same gap.

Drop the counter alongside the deque at all three sites (evict, per-thread
reset, full reset). The window deque and its mirror Counter now stay in sync.
