[aio-fleetbot]

Summary

• Updates upstream pins for sure-aio.

What changed

• Sure Alpha: 0.7.2-alpha.7 -> 0.7.2-alpha.10 plus image digest refresh
• Release notes: https://github.com/we-promise/sure/releases
• Source repo paths reviewed/generated:
  • CHANGELOG.alpha.md
  • Dockerfile.alpha

Why

• Keeps the AIO wrapper aligned with upstream while preserving human review.
• Source repo changes are validated here first; catalog sync follows the validated source repo and never starts in awesome-unraid.

Validation

• Generated by aio-fleet upstream monitor; central checks should run on this PR.
• The generated commit must be verified/signed before branch protection allows merge.
