Default to type-aware linting

In the past, we used non-type-aware linting in our pre-push hook, as
well as in `npm test`. This was for performance reasons.

In practice, though, we use an eslint cache, which makes even
type-aware incremental linting instantaneous. My rule is that you
should be able to make a small change and lint in under 10 seconds, and
`npm test` should take under 30 seconds, and linting with no changes
(for the pre-push hook) should be under 2 seconds. This is still true
for type-aware linting, so there's no actual need for fast linting.

We've also switched to using `--max-warnings 0` to convert warnings to
errors. This seems to allow them to use the same cache file.

A big improvement here is that `npm test` should now be enough for
testing. I think everyone ran `npm run full-test` for a while because
`npm test` didn't have type-aware lint errors, but now that it does,
you'll be able to use it again and have your tests run a lot faster.
