explain-state

Summarize what nyann currently sees in this repo: stack detection, active profile, branching strategy, hook status, CLAUDE.md, and recent commits. TRIGGER when the user says "what does nyann think is set up here", "show nyann state", "explain the setup", "what's the current config", "what's the active profile", "describe this repo's nyann setup", "what's wired up", "show me the repo state", "/nyann:explain-state". Do NOT trigger on "what does this repo do" (that's a docs intent — route to CLAUDE.md / README), "is this repo healthy" (that's the `doctor` skill), or "what's in the X profile" (that's `inspect-profile`).

适合你，如果想知道 nyann 在当前仓库里看到了什么设置。
