### Description This PR introduces sliding window support to the `limit-count` plugin for Redis- and Redis Cluster–based policies while preserving the existing fixed window behavior by default. - Adds a new `window_type` option (`fixed` | `sliding`) to the `limit-count` plugin configuration, with `fixed` as the default for backward compatibility. - Enforces that `window_type = "sliding"` is only allowed when the `policy` is `redis` or `redis-cluster` to avoid unsupported combinations. - Extends the Redis (`limit-count-redis`) and Redis Cluster (`limit-count-redis-cluster`) implementations to enforce an exact N requests per rolling time window when `window_type` is set to `sliding`. - Adds test cases for the sliding window behavior in both Redis and Redis Cluster modes (`limit-count-redis-sliding.t`, `limit-count-redis-cluster-sliding.t`). - Updates the English and Chinese `limit-count` plugin documentation to describe the new `window_type` option, its behavior, and performance considerations when using sliding windows. The default behavior remains unchanged for existing configurations that do not specify `window_type` or continue to use `fixed`. #### Which issue(s) this PR fixes: Fixes # ### Checklist - [x] I have explained the need for this PR and the problem it solves - [x] I have explained the changes or the new features added to this PR - [x] I have added tests corresponding to this change - [x] I have updated the documentation to reflect this change - [x] I have verified that this change is backward compatible (If not, please discuss on the [APISIX mailing list](https://github.com/apache/apisix/tree/master#community) first) -- This is an automated message from the Apache Git Service.
