v1.2.0

Fixed duplicate comments and rate-limit failures on pull requests with many comments (CP-16628, #4):

• Reads all pages of existing comments, so reruns no longer repost the action's own comments on PRs with more than 30.
• Posts new comments as reviews of up to 20, and waits and retries when GitHub rate-limits a batch (up to 5 minutes per run).
• GitHub API and network failures log a warning instead of failing the check, so failure_exit_code: 0 stays non-blocking.
• An offense whose comment went outdated after a push is commented on again.

v1.1.0

Added options for overriding the exit code and suppressing the outside-diff comment.
