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.

Workflow (MANDATORY, fully automatic)
