ci-watcher-loops

Patterns for setting up reliable agent self-feedback when waiting on long-running GitHub Actions workflows in this repo (cms-publish-loop-host, deploy-production, e2e matrix). The default temptation — RUN=$(gh workflow run X && gh run list --jq ...) chained into a polling until loop — silently breaks because both commands' stdout concatenate into the variable. Use the patterns here when chaining "wait for PR merge → trigger workflow → watch completion" or any multi-step CI poll. Trigger when the user asks to watch a workflow, set up a feedback loop, monitor PR completion, or any "let me know when X finishes" task that involves the gh CLI.
