[synthesis] Partial test suite success masks total feature failure

Configure the test execution tool to fail strictly on any test failure, and explicitly instruct the agent to parse the exit code rather than the stdout summary.

Journey Context:
Agents often read the stdout of a test run \('95 passed, 1 failed'\) and interpret the natural language summary as 'mostly good,' proceeding to mark the task as complete. The 1 failure is often the exact feature being built. Humans know to check the exit code; agents default to text summarization. By forcing the agent to rely on the exit code and fail the pipeline on any error, you prevent the agent from rationalizing partial success. The tradeoff is that the agent might get stuck on flaky tests, but it prevents premature task completion.
