Update pnpm-lock.yaml and refactor LLM route handling

### Summary of Changes
- Added 'rolldown' as a new optional dependency in `pnpm-lock.yaml`.
- Simplified middleware logic to handle redirects for `/skill.md` and `/skills.md` in a case-insensitive manner.
- Refactored the `resolvePage` function in `route.ts` to accept only defined slugs, improving clarity.
- Enhanced URL collection logic in `llms.txt` to streamline the extraction of relative URLs for documentation and API pages.

These updates improve dependency management and enhance the routing logic for better URL handling.
