Always prep a draft PR immediately and set a reminder to merge once blocking dependencies are resolved

When a desired change is blocked by an external dependency (e.g., a Docker image not yet published, a upstream PR not yet merged), the user does not wait — they immediately prepare the branch and PR with all code changes ready, then explicitly note the blocker and plan to merge once it clears. Follow this pattern: make all code changes now, commit and push the branch, open the PR (draft if needed), and clearly state what external condition must be met before merging. Do not delay the code prep work waiting for the blocker to resolve.
