[BUG]GitHub CI onboarding skill does not close the required verification loop

Problem

github_ci_fix_onboarding instructs the agent to stop when checks are pending and wait for the user.

This conflicts with the repository's mandatory CI policy, which requires the agent to monitor checks after every push, inspect failures, fix them, and repeat until required checks are green.

The skill can therefore report an incomplete workflow as successfully onboarded.

Affected code

• core/agent_harness/prompts/skills/github_ci_fix_onboarding/SKILL.md
• AGENTS.md
• CI.md

Expected behavior

The onboarding flow should continue monitoring until checks reach a terminal state and should not report success while checks are pending or failing.

Suggested fix

Require the skill to use the repository's standard CI loop:

1. Monitor gh pr checks --watch.
2. Pull failed logs.
3. Fix the root cause.
4. Run focused local checks.
5. Push and repeat.

Acceptance criteria

• Pending checks do not end the workflow.
• Failed checks trigger another fix cycle.
• Success is reported only when required checks are green.
