docs(autopilot): auto-open review artifacts at human review gates

[jankneumann]

Motivation

• Ensure reviewers can open proposal/design/spec/tasks artifacts before answering human approval questions at autopilot gates so the acceptance prompt doesn't block exploratory review.

Description

• Update skills/autopilot/SKILL.md to invoke /review-artifacts <change-id> automatically before the PLAN-phase proposal-approval prompt and before the DONE/merge-approval questions; change is documentation-only (docs(autopilot): auto-open review artifacts at human review gates).

Testing

• No automated tests were required or run for this documentation-only change; only a local commit was created (skills/autopilot/SKILL.md).

Make review-artifacts invocation best-effort

This new step makes /autopilot unconditionally call /review-artifacts at approval gates, but that helper is documented as local-only and depends on the code CLI (.agents/skills/review-artifacts/SKILL.md notes cloud harnesses lack it and exit 127). In cloud/CI-style runs, this can fail right before the human gate and block or derail the workflow instead of cleanly prompting for approval. Please gate this behind local capability checks (or explicitly treat failures as non-fatal) in both approval-gate insertions.
