The new \`docker\` Playwright project needs a Docker daemon and the
linux/amd64 agentctl + mock-agent binaries bind-mounted into containers.
Pin the existing sharded job to chromium + mobile-chrome so the docker
project no longer leaks into every shard (where it would fail seeding
without KANDEV_DOCKER_ENABLED), and add an \`e2e-docker\` job that:
- Verifies the Docker daemon is reachable on the runner.
- Downloads the same backend artifact (now including the linux helper
binaries, built via \`make build-backend-linux-helpers\`).
- Runs \`playwright test --project=docker\` with KANDEV_E2E_DOCKER=1.
- Cleans up any kandev-managed containers at teardown so leaks don't
poison the next run.
