Instruct agents to prefer yarn test:ci over yarn test

[rak-phillip]

Summary

This resolves an issue where Gemini CLI can hang indefinitely when the tool runs yarn test.

Occurred changes and/or fixed issues

• Instruct agents to prefer yarn test:ci over yarn test

Technical notes summary

yarn test:ci works better with tools like Gemini CLI because it will run tests once and exit. yarn test runs Jest in watch mode, which can cause CLI agents to hang while awaiting test output.

Areas or cases that should be tested

Try instructing Gemini CLI to write a simple sanity test. When the test runs to validate that it passes, the CLI should gather the results and finish its task.

Areas which could experience regressions

Previously, when running yarn test, Gemini CLI could hang indefinitely while waiting for the watched tests to complete. This single run approach should improve the overall behavior.
