skill-optimizer — 自动优化 lovstudio skill 并维护版本与 changelog

Runs a lint → fix → bump → changelog pipeline on an existing skill in this repo. Fully automatic — no interactive prompts. Every run produces a concrete version bump and a new CHANGELOG.md entry so optimization history is traceable.

When to Use

User mentioned a concrete problem with an existing skill in this conversation (wrong trigger phrases, stale CLI flags, missing README badge, etc.) and wants it fixed.
User asks to "audit", "polish", "refine", "刷一遍" an existing skill.
User explicitly asks to bump a skill's version or update its changelog.
Proactively after another skill has been modified meaningfully — run this to record the change with a version bump.
