build: publish built JavaScript so apps don't compile the specs

The package's react-native and source fields pointed at src, so apps
compiled the decorated .nitro.ts specs with their own Babel config,
which React Native's default preset can't parse. The entry points now
point at lib, and bob parses the specs through per-target Babel
configs. main points at the CommonJS build that bob validates it
against, and CI builds the package so a broken build shows up before
a release.
