The Run Claude Code Review step passed an invalid PR ref
(owner/repo/pull/N) which gh interprets as a branch name, causing
early gh pr view failures. More importantly, the prompt omitted
--comment, so the code-review plugin only displayed findings in
terminal output and never invoked gh pr comment to post to the PR.
Switch to a full PR URL and add --comment so the plugin posts the
review during the session, which also routes around upstream bugs
anthropics/claude-code-action#1061 and #1087 where the action's
post-step capture can silently drop output on issue_comment triggers.
