The --comment flag was passed. After producing the findings list, if the
review target is a GitHub PR, post each finding as an inline PR comment via
mcp__github_inline_comment__create_inline_comment (one call per finding;
include a suggestion block only when it fully fixes the issue). If that tool
is not available in this session, fall back to gh api (repos/{owner}/{repo}/pulls/{pr}/comments)
or print the findings instead. If the target is not a PR, print the findings
to the terminal and note that --comment was ignored.
