Eliminate all code paths, configuration, and documentation related to running
without authentication. Require AUTH_SECRET and BASE_URL at startup, updating
middleware, server logic, and runtime checks to assume auth is always enabled.
Simplify onboarding, settings, and test helpers to reflect mandatory auth.
Update environment examples, Docker and deployment docs, and CI/test configs.
Remove no-auth-specific UI flows, test cases, and feature toggles.
move worker startup logic from server.ts to runtime.ts for better modularity
add worker-loop-policy.ts for loop control abstraction
delete legacy unit tests under tests/unit/ related to compute worker and control-plane
add vitest config and test directories for compute-core and compute-worker
add vitest workflow for CI
update package.json scripts for new test commands and add vitest as dev dependency
BREAKING CHANGE: worker entrypoint is now compute/worker/src/runtime.ts instead of server.ts; legacy Playwright-based unit tests for compute worker are removed in favor of Vitest
