## Summary
- Adds `claude` to the CLA Assistant allowlist to fix CLA check failures
on PRs authored with Claude Code

## Problem
PRs authored with Claude Code (like #2268) have commits with the
`claude` GitHub user (email: `noreply@anthropic.com`) as an author via
the `Co-Authored-By` trailer. The CLA Assistant requires all commit
authors to sign the CLA, but Claude (the AI) cannot sign a CLA, causing
the check to always fail.

## Solution
The CLA Assistant action supports an `allowlist` parameter to exclude
specific users from the CLA requirement. This PR adds `claude` to that
allowlist.

## Test plan
- [x] Verify this PR's CLA check passes (it should, since this is the
fix)
- [ ] Verify subsequent Claude Code PRs pass the CLA check
