Add rate limiting to all API routes and cover it with tests

Plan
1. Create src/middleware/rateLimit.ts
2. Wire it into the router in api.ts
3. Add tests in tests/rateLimit.test.ts

✓ Created rateLimit.ts +64
✓ Edited api.ts +3 −1
✓ Created rateLimit.test.ts +41

✓ Tests passed — 27/27

All API routes now return 429 after 100 requests/minute per IP. Review the staged diff when ready.

switch it to Redis so it works across instances

Good call for multi-instance deploys. Updating the middleware to use a Redis sliding window — see the inline diff in rateLimit.ts…
