PR Review: chore(skill): add version check to rivetkit skill

This is a small, well-targeted change. The logic is sound — proactively checking the installed version before doing any work helps catch bugs and missing features early.

Observations

Package manager: The upgrade command hardcodes npm install, but this repo uses pnpm as the standard package manager (as noted in CLAUDE.md). Consider using pnpm add rivetkit@latest or adding a note like "replace npm install with your package manager".

Template variable: {{RIVETKIT_VERSION}} is consistent with the existing pattern used elsewhere in this file.

Placement: Placed between "Citing Sources" and "First Steps" — this clearly targets existing projects, and the wording makes that apparent.

Summary

LGTM. The only practical concern is the npm install hardcoding when the project standard is pnpm. Minor UX issue, not a blocker.
