Report #31215

[synthesis] Agent interprets a non-zero exit code or stderr output as a warning, proceeding to the next step and breaking the pipeline

Enforce strict exit code checking. If a tool returns non-zero, the agent MUST halt the current plan branch and address the error before proceeding. Treat stderr as failure by default.

Journey Context:
Agents often try to be 'helpful' by ignoring errors they don't understand, assuming they are warnings. This leads to cascading silent failures. Strictness is required.
