作者自荐：dsh-fast

[PerryLink]

自荐说明（Self-recommendation）：

dsh-fast 是只读零侵入的性能诊断插件：会话加载耗时、spill 命中、压缩统计、上下文注入体量、缓存命中率；/fast 命令 + fast_report 工具，异步采样不占模型路径。适合想看清 DSH 运行性能瓶颈、又不想改动任何行为的用户。

Read-only performance diagnostics: session load timing, spill hits, compaction stats, context-injection volume, and cache-hit rate via the /fast command and fast_report tool, sampled asynchronously off the model path. For DSH users who want to see performance bottlenecks without changing behavior.

改动：

• 仓库：https://github.com/PerryLink/dsh-fast（公开、dsh-plugin topic、Apache-2.0、五语 README、v0.1.0 Release；npm 尚未发布）
• SHOWCASE.md「作者自荐」与「Author showcase」末尾各追加一行（中英对应）；列表满 30，先进先出移除最旧一条 dsh-vision-proxy
• README.md / README_EN.md 首页自荐预览同步为最近 10 条
• 本地自检 node scripts/validate-curated.mjs 通过
