testing/testing_rate_limiter.ts

Test-only RateLimiter subclass with bucket tracking + reset_all.
Production code never instantiates this; test binaries swap it in for
production RateLimiter so _testing_reset can clear every bucket
between cases. Mirrors the TestingArgon2idHasher pattern from the
Rust spine — same call surface as the production class, plus test-only
knobs (reset_all, tracked_keys).
Constructor + every overridden method preserve production semantics
by delegating to super.* after tracking; reset_all walks the
tracked-keys set and calls super.reset per entry. Tests that depend
on burst behavior get identical results between production and test
instantiations.
Usage in a test binary:
import {TestingRateLimiter} from '@fuzdev/fuz_app/testing/testing_rate_limiter.js';

const limiter = new TestingRateLimiter(default_login_ip_rate_limit);
await create_app_server({backend, ip_rate_limiter: limiter, ...});

// Inside the `_testing_reset` handler's `reset_state`:
limiter.reset_all();

RateLimiter plus bucket tracking. Every check/record call adds
its key to #seen_keys; reset removes it; reset_all clears every
tracked bucket. Drop-in replacement anywhere a RateLimiter is
expected — the type is nominally compatible via subclassing.

Clear every bucket this limiter has been asked about. Idempotent;
safe to call before any check/record activity. Designed to be invoked
from a _testing_reset handler's reset_state callback so the test
binary's rate-limit buckets don't leak across test cases.
