Reduce CI test output by using dots reporter

[robobun]

Summary

• Adds --reporter=dots to bun test invocations in scripts/runner.node.mjs to reduce CI log output volume
• The dots reporter prints a single character per test (. for pass, X for fail) instead of full test names
• When JUnit reporting is also enabled, both reporters stack correctly — dots goes to stdout, JUnit writes to file

Test plan

• Verify CI builds run with dots reporter and produce smaller logs
• Verify JUnit reports are still generated correctly when --junit is enabled
