docs: add faster PR workflows planning document (#2739)

## Summary Add a comprehensive planning document outlining an initiative to improve the speed of landing PRs for maintainers by optimizing the CI pipeline, automating the fix-and-retry loop, and improving developer feedback during wait times. The plan covers: - CI pipeline optimizations for self-hosted macOS ARM64 runners (caching, job consolidation) - Auto-trigger fix loop for privileged author PRs (remove label requirement) - Tiered test selection based on changed files - PR status watcher for terminal notifications - Unified `/pr` skill entry point - Move pr-review-responder to self-hosted runners The plan is structured in four implementation phases: instrumentation, CI quick wins, auto-fix loop enhancements, and developer experience improvements. It includes risk assessments, testing strategies, and decision logs. ## Test plan - Verify the document is correctly formatted and renders as markdown - Review the content for clarity and alignment with project goals - Confirm all phases, user stories, and technical components are clearly described 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2739" target="_blank"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://static.devin.ai/assets/gh-open-in-devin-review-dark.svg?v=1"> <img src="https://static.devin.ai/assets/gh-open-in-devin-review-light.svg?v=1" alt="Open with Devin"> </picture> </a>
