test: use quiet dot reporters and show output only for failing tests

Switch vitest packages (ai, agent, coding-agent) to the dot reporter
with silent: passed-only so passing tests stay quiet while failing
tests still print their console output and full diffs. Add the
github-actions reporter on CI for inline annotations. Switch the tui
node:test runner to the dot reporter as well.
