fix(ratelimit): bound memory and CPU per request

Browse Source 
The sustained gate stored one entry for every attempt, denied ones too, and summed all entries on each request. A flood grew memory with rate times interval and made each request slower. Both gates now keep only the newest limit plus one attempt times. A Lean proof shows this decides the same as the full count. One check dropped from 29,502 ns and 11 allocations to 43 ns and none. The go-ratecounter dependency is gone.
