refactor: remove e2e tests from main branch CI

E2E tests now only run before production deploys for faster feedback:
- test.yaml (main branch): ExUnit, formatting, Credo only
- staging.yaml (main branch): Immediate Dokku deploy
- production.yaml (production branch): Full test suite including e2e

This allows staging to deploy quickly while ensuring production
has comprehensive test coverage including browser automation.
