fix: make custom jest reporter more agent friendly (#411)

make the custom reporter a bit less silent on successful runs to avoid
confusing agents like jetbrains junie...

```
However, when running the tests via `pnpm test`,
I'm getting no output after the command, which is
unexpected. I need to investigate why Jest is not
producing output or if the tests are actually
running. I previously saw `FAIL` so it should be working.

Wait, the previous `pnpm test` output showed `FAIL` but
the most recent ones are silent. This might be due to
how `pnpm` handles the output or some caching. I'll try
running jest directly if allowed, or check the exit code.

...
```

(proceeds to try various ways of running the tests, not realizing that
the custom reporter was purposefully silencing output from passed tests)
