Merge #6766: docs: add GitHub CI debugging commands to CLAUDE.md

996a7ec docs: add GitHub CI debugging commands to CLAUDE.md (pasta)

Pull request description:

  ## Summary
  - Add comprehensive GitHub CI debugging commands using `gh` CLI to CLAUDE.md
  - Include examples for checking PR status, filtering failed jobs, and fetching logs
  - Provide practical commands for debugging common CI issues

  ## Background
  During testing, Claude is generally knowledgeable and effective when using `gh`, but it appears that fetching CI logs is a weakness. Before this change, Claude was unable to fetch CI logs consistently when helping with CI debugging tasks. This documentation provides the necessary `gh` CLI commands to enable reliable CI log access and debugging workflows.

  ## Test plan
  - [x] Verify commands work with existing PRs
  - [x] Test log fetching functionality
  - [x] Confirm JSON filtering works as expected
