feat(code-review): add github review skill

[alex-alecu]

Summary

GitHub Code Reviewer runs now get a trusted skill that tells the agent how to read fresh pull request state and avoid old findings. The skill is added only for GitHub reviews and replaces any skill data sent by the caller, so GitLab reviews keep their current flow. It tells the reviewer to read every page of GitHub data, check the latest commit before writing, ignore stale line comments, and update the Kilo summary with only current issues.

Verification

1. Start a GitHub Cloud Code Reviewer run and confirm the session prompt starts with the github-cloud-review load cue.
2. Start a GitLab Cloud Code Reviewer run and confirm it keeps its original prompt and receives no runtime skill.
3. Review a pull request with old inline comments whose current line is gone and confirm fixed findings are not carried into the summary.

Reviewer Notes

No GitHub issue was listed in the plan. The main risk is prompt behavior: the skill wording should stay aligned with the allowed gh command patterns and the server-owned summary sections.
