v0.2.4 — 自动发布

首个通过 Trusted Publishing（OIDC）自动发布到 npm 的版本 / First release published
through Trusted Publishing (OIDC).

Added

• GitHub Release 发布后自动发包：.github/workflows/release.yml 用 id-token 向 npm 换取
  一次性凭证，仓库不保存任何 npm token / Publishing to npm is triggered by this Release;
  the workflow exchanges a GitHub Actions id-token for a one-time credential, and no npm
  token is stored.
• 发布前四道语义门禁：标签匹配、预发布状态一致、dist-tag 路由（预发布 → next）、
  latest 不回退；发布后回查 registry 确认可安装 / Four semantic gates before publishing
  (tag match, prerelease parity, dist-tag routing, no latest rollback) and a post-publish
  registry check.
• 新增 RELEASING.md
  记录一次性绑定与每次发版步骤 / Added RELEASING.md.
• README 增加 Awesome DSH Plugin 徽章与 powered by dsh 徽章 / README badges.

Install

dsh plugin --profile web add dsh-cache-hit-precision

本版无功能变更，仅发布流程与文档 / No behavior change in this release; automation and docs only.
