…7046) Sliding expiration: entries can now stay alive as long as they're being accessed, with an optional hard deadline. Useful for sessions or rate-limit windows.
Casting the setInterval return value with `as number` fails type-checking on newer Deno libs where it resolves to `Timeout` instead of `number` (TS2352). Coerce with `Number(...)` instead, matching the convention used in @std/async/delay. Co-authored-by: Cursor <cursoragent@cursor.com>

Fixes: #7175
New Rate limit module
This new module offers strategies for controlling how many operations can occur over time. Inspired by .NET’s
System.Threading.RateLimitingThe primary API is
createRateLimiter, a keyed rate limiter for the common case of "allow key X at most N requests per window." It supports fixed-window, sliding-window, token-bucket, and GCRA algorithms.For single-resource limiting, use the primitives:
createTokenBucket,createFixedWindow, andcreateSlidingWindow.The rate limiter supports both in-memory usage and Redis-backed storage for distributed rate limiting across multiple processes or deployments.
Depends on
@std/data-structures:Dequefor async queue management andRollingCounterfor sliding-window segment tracking.Planned future additions
Note
Recreates #7063, which was closed automatically when I accidentally deleted the head fork. The branch is identical to the original PR head.
