Add cross-repo dispatch to Claude Code Review (#26)

Use GitHub App token (CLAUDE_CI_APP_ID) for cross-repo access when
dispatching reviews via workflow_dispatch. Remove issue_comment,
pull_request_review_comment, and review_requested triggers since
org-level workflows don't propagate those events to other repos.
