## Summary
Adds `docs/guides/testing-local-changes.mdx` — a contributor guide explaining how to test unreleased CLI changes against real projects outside the monorepo.
**Covers:**
- `pnpm link --global` (recommended — makes `hyperframes` in `$PATH` point at your local build)
- `node` alias (no PATH changes)
- `npm pack` (test the exact artifact that would be published)
- Troubleshooting (`which hyperframes`, port conflicts, stale builds)
- Table of test scenarios for each bug category
Also registers the page in `docs/docs.json` so it appears in the Guides nav.
