ci: fix red radioSpeech assertion and add a test/typecheck pipeline

The suite was red on main: the SID test still expected the old
letter-by-letter spelling ("Mike Alfa Romeo...") after the pronunciation
change to speak named waypoints as words ("Marun seven Foxtrot"). Update the
stale assertion.

Add a GitHub Actions workflow: yarn install + yarn test as the required gate,
plus a non-blocking vue-tsc job (TS strict mode is still off — promote to
required after that cleanup). Suite now 80/80.
