Probe 6 (2026-05-08) showed git push failing twice with exit 1 and
zero visible output — the previous form `if cmd 2>&1; then` redirected
git's stderr to stdout where the entrypoint's stderr-only log capture
missed it. CP-side log showed only the bash `set -x` trace, not the
actual git error message (e.g., "Permission denied (publickey)" or
"remote: pre-receive hook rejected").
Refactor the push retry loop:
- Capture output to PUSH_OUT via $() with `2>&1`
- Wrap in set +e/set -e to detect non-zero without aborting
- echo PUSH_OUT to stderr (where set -x trace also goes) so the
entrypoint's stderr capture sees it
