Add user feedback endpoints and fix patchHandler bug

[Copilot]

Implements a minimal user feedback system with REST endpoints for submitting and retrieving feedback.

Changes

• feedbackHandler.js (new): Added POST /feedback and GET /feedback endpoints

  • In-memory storage with monotonic ID generation
  • Required message field, optional email field
  • Returns 201 on success, 400 on validation failure

• patchHandler.js: Fixed undefined asdasd() call causing crashes

  • Now returns proper response on PATCH requests

• index.js: Mounted feedback handler on root path

Usage

# Submit feedback
curl -X POST http://localhost:7000/feedback \
  -H "Content-Type: application/json" \
  -d '{"message": "Great app!", "email": "user@example.com"}'

# Retrieve all feedback
curl http://localhost:7000/feedback
