[q] update architecture diagram workflow to maintain scratchpad file

[github-actions]

Summary

Updates the daily-architecture-diagram workflow to maintain scratchpad/architecture.md in addition to creating GitHub issues.

Changes Made

.github/workflows/daily-architecture-diagram.md

1. Added create-pull-request safe-output — enables the agent to propose file updates via PR when the diagram changes
2. Added Scratchpad File section — instructs the agent to update scratchpad/architecture.md with the latest diagram after each run, including the date and source issue link

Behavior

• When the diagram changes: agent updates scratchpad/architecture.md via create-pull-request safe-output, creating a PR labeled architecture, diagram, documentation
• When the diagram is unchanged: agent calls noop and skips the scratchpad update

Validation

Compiled successfully with gh aw compile daily-architecture-diagram ✅

Closes #19177 (triggered by comment from @pelikhan)
