Fix: Remove pull_request trigger from reusable workflow (#1)

The claude-review.yml is a reusable workflow (workflow_call) and should
not have a pull_request trigger. Individual repos will call this workflow
via their own claude.yml files which contain the pull_request trigger.

This fixes the workflow file issue that was causing failures.
