Summary

• add a first-class okdev jobs command group for detached exec workflows, while keeping okdev exec --detach as the launcher and okdev exec-jobs as a compatibility alias
• group multi-pod detached launches under one logical job id and add grouped list, aggregated logs, wait, and stop flows with targeted coverage
• document the new jobs surface and keep partial per-pod query failures visible in command output

Test Plan

• go test ./internal/cli -count=1
• go test ./... -count=1
• /Users/jacky.he/work/okdev/.venv/bin/pre-commit run --all-files --hook-stage manual okdev-gofmt
