🛡️ Sentinel: [HIGH] Add CSRF protection to report-issue endpoint

Severity: HIGH
Vulnerability: The application was not protecting the POST /api/report-issue endpoint from Cross-Site Request Forgery (CSRF) attacks.
Impact: An attacker could host a malicious page that tricks an authenticated user's browser into submitting arbitrary issue reports to the repository via a forged POST request.
Fix: Added isSameOrigin validation from @/lib/security/rate-limit to explicitly validate the request Origin or Referer headers before processing the payload.
Verification: Added a test in src/app/api/report-issue/route.test.ts to ensure cross-origin requests are rejected with a 403 Forbidden status, and ran pnpm test to ensure it passes.

Added `isSameOrigin` validation from `@/lib/security/rate-limit` to the `POST /api/report-issue` endpoint to prevent Cross-Site Request Forgery (CSRF) attacks. Requests from external origins will now correctly receive a `403 Forbidden` response. Updated the associated test suite to assert the new CSRF protection behavior.

Pull request overview

Adds same-origin validation to the POST /api/report-issue Next.js App Router endpoint to mitigate CSRF, and extends the API test suite to ensure cross-origin POSTs are rejected.

Changes:

  • Enforced CSRF protection by rejecting cross-origin requests using isSameOrigin(request) before processing report payloads.
  • Updated report-issue route tests to include Origin by default and added a 403 test for cross-origin POSTs.
  • Documented the CSRF learning/prevention in .jules/sentinel.md.
