chore: stop CodeRabbit from reviewing automatically

[afonsojramos]

Summary

Adds .coderabbit.yaml so CodeRabbit no longer reviews pull requests in this repository automatically, posts review-status comments, or writes summaries into PR descriptions. Pullfrog reviews pull requests here, including the Submission review workflow for vault submissions. CodeRabbit still answers when mentioned with @coderabbitai. The repository file overrides the organization's CodeRabbit settings for this repository only.

Validation

• reviews.auto_review.enabled, reviews.review_status, and reviews.high_level_summary checked against CodeRabbit's published schema (schema.v2.json).
• pnpm fmt:check passes.
• CodeRabbit reads the configuration from the pull request's branch, so this pull request receiving no review or summary from it confirms the setting.

Reviewed changes

Reviewed the single-file config change disabling automatic CodeRabbit reviews on this branch.

• Disable auto reviews — sets reviews.auto_review.enabled: false so CodeRabbit only reviews when mentioned.
• Silence status noise — sets review_status and high_level_summary to false so no status comments or PR description summaries are posted.
