ci: install Ground Control Phase E workflow

[Brad-Edwards]

Summary

Installs the canonical Ground Control Phase E workflow generated by grndctl init 1.2.1. The workflow finalizes a delivery after its pull request merges by replaying the trusted Phase D readiness payload, posting the final report, and closing the linked issue.

This repository prerequisite currently blocks the Phase D readiness handoff for APTL PR #1170 because the workflow is absent from dev.

Why this is viable now

PR #1148 was closed because its proposed checkout workaround was needed while grndctl was unpublished. grndctl 1.2.1 is now published in the npm registry with integrity metadata, so this change uses the official generated workflow and its exact version pin. It does not revive the workaround.

Scope

• Add .github/workflows/ground-control-phase-e.yml exactly as generated by grndctl init 1.2.1.
• Record the new tracked path in the repository inventory.

Verification

• grndctl doctor reports Phase E workflow installed.
• Targeted repository tests: 114 passed, 1 skipped.
• Staged-file pre-commit hooks passed.
