Free Vite and SSR ports and clear stale pidfile in conductor run script (#7)

Why: starting bin/dev would frequently fail because port 3036 (Vite) or
13714 (SSR) was still bound from a previous run, or because a stale
tmp/pids/server.pid blocked Rails from booting. Killing only :3000 left
those failure modes intact.
