Add CodeRabbit review configuration

[brendonthiede]

Adds .coderabbit.yaml, validated against CodeRabbit's schema v2 (0 errors).

• Scope: skips vendor/ (pinned UMDs), images, dist/, and the lockfile.
• Per-path review rules for the invariants most worth checking. These rules only point at CLAUDE.md, which CodeRabbit already reads as a coding guideline by default:
  • background.js: the token never leaks into errors, fetch errors are only treated as "empty repo" when the branch is missing, commit deletion and protection rules, and a bounded push retry.
  • inject.js: apply-files is a full sync that deletes, viewState/uuid are preserved, the sha256 matches content.js, and write-files-live stays best effort.
  • Pure helpers: no DOM, blocksplice.js never throws, and the bundle-hint guard must not be constant-folded.
  • Content scripts: load order and the snapshot-first safety rail for robot-setup updates.
  • manifest.json: the localhost grant is intentional.
  • Tests: real git/python3/unzip binaries on purpose.
  • Release workflow: Chrome Web Store v2 API details.
• Checks: docstring coverage is off, since the codebase uses comments rather than JSDoc. A custom "Docs track contracts" warning fires when message ops, bridge ops, storage keys, or content-script order change without a CLAUDE.md update.
• Noise: chill profile, no poem or fortune. actionlint, shellcheck, gitleaks, markdownlint, and yamllint are enabled explicitly.
