The GUI README tells contributors to run `npx tsc --noEmit` and `npm run build`
starts with `tsc`, but CI never runs either — a type error ships green today
and only surfaces when someone next builds a bundle locally. Add the check as
one step inside the existing gui-unit job so it reuses that job's npm ci and
costs no extra runner.
Verified locally: `npx tsc --noEmit` exits 0 on current main, and the vitest
suite (82 tests) still passes.

Release workflow adapted to the root layout (no monorepo paths, no .pth venv wiring).
New CI runs the coworker pytest suite and GUI unit tests; e2e joins once the inherited failures are fixed.
