[WIP] Document SideRepoOps development process

[Copilot]

Documentation Plan: SideRepoOps Development Process

• Create docs/src/content/docs/guides/siderepoops.md documenting the SideRepoOps pattern
  • Overview and when to use SideRepoOps
  • How it differs from MultiRepoOps
  • Setup requirements (separate repo, PAT configuration)
  • Workflow configuration for targeting other repos
  • GitHub token setup for private repo access
  • Manual issue transfer workflow
  • Example workflows
  • Best practices
• Update sidebar configuration in docs/astro.config.mjs to add SideRepoOps to Design Patterns
• Verify documentation builds successfully (builds successfully with all 61 pages)
• Final review and cleanup

Summary

Successfully documented the SideRepoOps development pattern, which enables running agentic workflows from a separate repository that targets a main codebase. The documentation includes:

✅ Complete guide with setup instructions, workflow examples, and best practices
✅ Clear distinction from MultiRepoOps pattern
✅ PAT configuration for private repository access
✅ Issue management and transfer workflows
✅ Troubleshooting section for common problems
✅ Advanced topics including GitHub Apps and multi-target scenarios
✅ Successfully builds with Astro Starlight (61 pages)
✅ Added to Design Patterns section in sidebar navigation

Original prompt

Document the "SideRepoOps" development process:

One can use a separate repo to run agentic workflow in order to minimize the noise of generated AI items or keep the workflows private .

• a (public/private) repository contains the agentic workflows which run in the actions of that workflow (this repo can be empty)
• the PAT github token is needed to access the main repo if private
• the agentic workflow need to mention that they need to target another repositories
• generated issues can be manually transferred as needed.
