Start the "E2E Until Green" loop.

Goal: E2E suite passes
Max iterations: 10
Between iterations run: npm run test:e2e
Exit when: E2E command exits 0

Step 1: Run E2E tests. Fix the first failing spec, then repeat.

Self-pace this loop. After each iteration, run the check command, read the output, and only continue if the exit condition is not met. Stop when the exit condition passes or max iterations is reached. Give a short status update each pass.
