Stack detection for curriculum router

Run before Phase 2 route matching.

Read package.json

Signal	stack value	Prefer skills
"next" in dependencies	next	devlearn-next → devlearn-react → devlearn-deploy
"react" (no next)	react	devlearn-react → devlearn-javascript
"vite" or no framework	vanilla	devlearn-html-css → devlearn-javascript

Update DEVLEARN.md stack: when autodetect if file writable.

Route overrides

stack	Instead of vanilla path
next	Skip pure html-css unless user needs fundamentals; start next + react
react	react after quick js refresh if needed
vanilla	existing html-css → js chain

package.json absent

Assume vanilla static site path unless user names a framework.

Example router output (Next detected)

**Detected stack:** Next.js (from package.json)

**Learn next:**
1. `/devlearn-next` — routing and server/client split in your app
2. `/devlearn-react` — components and state for UI
3. `/devlearn-deploy` — Vercel-style deploy
