## Summary
- Switch `claude-pr-review` workflow from `multi-pr-review` to
`swarm-pr-review` skill
- Add warnings in both skill SKILL.md files to save intermediate files
to the working directory (`./pr_diff.patch`) instead of `/tmp/`, which
is blocked by `claude-code-action` security sandboxing in CI
- Document the CI file access restriction in `rules/git-workflow.md`

Fixes the `cat in '/tmp/pr_*_diff.patch' was blocked` error:

#skip-bugbot

## Test plan
- [ ] Verify PR review workflow triggers on a new PR and doesn't hit the
`/tmp/` file access error
- [ ] Confirm the swarm-pr-review skill posts a review summary comment

## Summary by cubic
Switched the CI PR review workflow to use swarm-pr-review and fixed the
/tmp file access block in claude-code-action. Updated skill docs and git
workflow rules to save PR diffs in the repo working directory (e.g.,
./pr_diff.patch) instead of /tmp, resolving the “cat in
'/tmp/pr_*_diff.patch' was blocked” error.

<sup>Written for commit 449c7b02b4bacad12a659177d1f6a4db949fc7ab.
