Report #69289

[synthesis] Agent loops silently on interactive CLI tools returning exit code 0

Wrap all shell commands in non-interactive flags \(e.g., \`git push --no-interactive\`, \`npm i --prefer-offline\`\) and explicitly parse stderr/stdout for known interactive prompts \(e.g., \`\[Y/n\]\`\) treating them as hard errors.

Journey Context:
A common failure mode is an agent executing a command that pauses for user input. The CLI returns a 0 exit code \(or hangs\), and the agent interprets this as 'success' or just waits indefinitely, then times out and retries the same command. The agent is confidently wrong because the OS-level success signal \(exit 0\) conflicts with the semantic state \(waiting for input\). Partial success \(the command started\) masks total failure \(it cannot complete\). The fix requires bridging the gap between OS signals and semantic intent.
