ChromaPrint3D

Help the operator publish, list, and remove user-visible announcements on ChromaPrint3D. Use when the user mentions publishing an announcement, posting a notice, scheduling a maintenance banner, creating an announcement, or anything related to the `/api/v1/announcements` API and the `scripts/announce.sh` tool. This skill should NOT be used to deploy new versions — pair it with `release-version` when notifying users ahead of a scheduled upgrade.

Guide the agent through ChromaPrint3D release workflows including preview and stable releases. Orchestrates version bump scripts, writes user-facing changelogs (version-manifest.json) in both Chinese and English, and creates release PRs. Use when the user mentions releasing, publishing, bumping version, creating a preview/rc release, writing changelogs, or generating version-manifest.
