ci: skip claude.yml when comment is '@claude review'

Comments starting with '@claude review' are handled by the hosted
code-review webhook, which creates a dedicated check run. Running this
workflow on the same trigger causes both systems to respond to one
comment — the GHA run then fails on fork PRs because it tries to fetch
the fork branch from origin.
