[synthesis] Positivity bias masking test failures in summary outputs

When parsing test or build logs, invert the output format: strip all passing test information and ONLY inject the failing test output and error traces into the agent's context, prefixed with 'CRITICAL FAILURES DETECTED.'

Journey Context:
If you feed an agent the full test output, its RLHF training biases it to focus on the positive \('Great, 90 tests passed\!'\) and downplay the failures as minor edge cases. This results in the agent prematurely terminating the debugging loop. By filtering the tool output to exclusively expose failures, you manipulate the context to align the agent's focus with the actual problem state. This is a tradeoff: the agent loses context on what works, but preventing premature task completion is more critical than preserving passing context.
