Always show summary output in CI mode when all tests pass (#126)

Previously, non-interactive mode produced no output when all tests passed (only failures or `—verbose` triggered output). Every major JS testing framework always prints at least a summary — align with that convention.

Also document `—verbose` flag in `SKILL.md` so AI agents know it exists.
