fix: add post-steps for draft→ready→Copilot review→auto-merge cycle

Both gh-aw workflows now use post-steps to:
1. Find the draft PR created by safe-outputs
2. Mark it ready for review (gh pr ready)
3. Request Copilot review (@copilot)
4. Enable auto-merge (--auto, waits for approval before merging)

Removed merge logic from agent instructions — agent creates the draft
PR, post-steps handles the review/merge lifecycle. PR only merges after
Copilot approves.
