Release v7.125.1

Changed

• Engineering guidance now says to verify locally, not through CI: build, specification, lint and frontend gates run on the developer machine before a push, and CI is the final confirmation before merge and deploy. On a shared machine, agents cap build and spec parallelism and run one heavy phase at a time.
• A pull request is opened once, when the work is verified, instead of early or kept alive with pushes. Related work goes into one PR, opened by the orchestrator rather than by each sub-agent. The ship-changes prompt and the orchestrator agent say the same.
• Agents assign every pull request they open to the user they run for (gh pr create --assignee @me), extending the existing issue-claiming rule.
• Run cratis ai update to receive the changed rules, prompt and agents.
