Harden Impeccable Skills Reviewer against external skill source failures

[Copilot]

The Impeccable Skills Reviewer workflow failed when needex/skills discovery or installation errored, causing the whole review job to stop before producing feedback. This change makes external skill loading non-blocking so the reviewer can still run and produce actionable output.

• Install step: fail-open behavior for external skills

  • Add SKILLS_LIST temp file for discovered skill names.
  • If skill discovery fails (gh api repos/${SKILLS_SRC}/contents/skills), emit a warning and continue.
  • If individual gh skill install calls fail, emit warnings per skill and continue.
  • If no SKILL.md files are installed, warn instead of exiting.

• Reviewer prompt: explicit fallback mode

  • Add guidance to proceed with a normal high-signal review (correctness/security-first) when no external skills are available.

• Generated workflow sync

  • Recompiled lockfile to reflect the source workflow behavior change.

if gh api "repos/${SKILLS_SRC}/contents/skills" --jq '[.[] | select(.type == "dir") | .name] | .[]' > "${SKILLS_LIST}"; then
  while IFS= read -r skill; do
    gh skill install "${SKILLS_SRC}" "$skill" --dir "${SKILLS_DST}" --force || \
      echo "::warning::Failed to install skill '${skill}' from ${SKILLS_SRC}; continuing."
  done < "${SKILLS_LIST}"
else
  echo "::warning::Failed to discover skills from ${SKILLS_SRC}; continuing without external skills."
fi

Pull request overview

This PR hardens the “Impeccable Skills Reviewer” GitHub Actions workflow so that failures to discover or install external skills from needex/skills do not abort the review job, allowing the reviewer to continue and still produce feedback.

Changes:

• Make external skill discovery/install fail-open (warnings instead of failing the job), including warning when zero skills are installed.
• Update the reviewer prompt to explicitly proceed with a standard correctness/security-first review when no external skills are available.
• Recompile the generated .lock.yml to sync the runtime behavior.
