When codex exec receives a prompt as a positional argument, it still
tries to read additional input from stdin (prints 'Reading additional
input from stdin...'). With stdio stdin set to 'ignore' or default,
codex blocks indefinitely waiting for stdin that never comes.
Fix: use stdio ['pipe', 'pipe', 'pipe'] and immediately close stdin
via child.stdin.end() in both execute.ts (sync) and jobs.ts (async).
This signals EOF to codex so it proceeds with the positional prompt.
Codex writes informational ERROR messages about ReasoningSummaryDelta
to stderr even on successful execution (exit code 0). The OpenClaw
agent misinterprets this non-empty stderr as a failure.
- Add filterStderrNoise() to strip known codex noise patterns from
stderr when exit code is 0
- Preserve raw stderr in DebugInfo.rawStderr when --debug is active
- Add 5 new tests covering noise filtering, preservation on failure,
debug raw output, and non-codex client passthrough
