Add CodeRabbit config to limit review frequency

[scalinity]

Summary

• Adds .coderabbit.yaml configuration to reduce CodeRabbit review frequency and usage
• Skips draft PRs to avoid reviewing work-in-progress commits
• Excludes documentation files (.md, .txt), license, and lock files from reviews
• Disables poems and request_changes workflow for more concise output

This completes the work started in #17 (which was closed without merging).

Test plan

• Verify CodeRabbit picks up the new config on the next PR
• Confirm draft PRs are no longer auto-reviewed
• Check that markdown files are excluded from reviews

📝 Walkthrough

Walkthrough

This PR introduces a new .coderabbit.yaml configuration file that establishes CodeRabbit review behavior for the repository. It sets the language to en-US, enables automated reviews on direct non-draft commits to the main branch, defines path filters to exclude documentation and package manager files from review scope, and enables automatic chat replies.

Changes

CodeRabbit Configuration Setup

Layer / File(s)	Summary
CodeRabbit configuration file .coderabbit.yaml	Establishes top-level schema, language (en-US), and early-access settings; configures auto-review for non-draft direct commits to main with presentation toggles and path filters excluding markdown, licenses, gitignores, and lockfiles; disables request-changes workflow and poem output; enables walkthrough collapsing and automatic chat replies.

Disable incremental reviews explicitly

If the intent is to require manual triggers after the initial review, this setting does not do it: CodeRabbit's auto_incremental_review defaults to true, so every new push to an eligible PR is still reviewed automatically, and base_branches only controls target-branch eligibility. Add auto_incremental_review: false under reviews.auto_review to actually stop per-push incremental reviews. Reference checked: https://docs.coderabbit.ai/configuration/auto-review#incremental-review

Keep setup docs in review scope

This excludes every Markdown file from automated reviews, including docs/SETUP.md, but this repository's review policy requires setup docs to stay in sync with the actual Slack env vars and slash command names. With this filter, a PR that changes only the Slack setup instructions will not get CodeRabbit coverage for that required consistency check, so narrow the Markdown exclusion or explicitly include docs/SETUP.md.
