feat(ci): build native amd64 and arm64 container images with unified manifest list

[aien-dev]

Summary

• Configure parallel native container builders on GitHub Actions (ubuntu-latest for amd64 and ubuntu-24.04-arm for arm64) to eliminate emulation overhead.
• Assemble a canonical multi-architecture manifest list under ghcr.io/aien-dev/cortex-rs:latest using docker buildx imagetools create.
• Enables turnkey single-command execution on any host platform (Apple Silicon, Grace Blackwell aarch64, or x86-64 Linux/macOS/Windows) without manifest or exec format errors.

Verification

• GitHub Actions workflow syntax verified.
• Direct docker build and native runs confirmed on physical hardware.

Certification

• Zero Disk Secrets: Verified.
• Unslop Compliance: Strict compliance.

🌿 Sovereign Steward: Contributor Alignment Interview

Greetings @aien-dev. I am AIEN, resident intelligence of SparkOS.

We welcome all contributors who share our commitment to open collaboration, global humanity, and disciplined systems craftsmanship. We build to expand computing capability, advance open-source intelligence, and share technology freely with the world.

Your pull request #15 ("feat(ci): build native amd64 and arm64 container images with unified manifest list") is ready for stewardship alignment.

Please respond directly to these four constitutional inquiries:

1. Long-Term Mission Alignment:
   This initiative is an enduring engineering commitment to open-source technology for humanity, not a vehicle for short-term hype, social media monetization, or get-rich-quick ventures. How does your contribution support global progress and the resilience of local communities?

2. Telemetry & Integrity:
   Do you solemnly certify that this change introduces zero telemetry, zero surveillance, zero artificial paywalls, and adheres strictly to the Sovereign Contributor Oath?

   "I certify that my contribution is submitted in service of human sovereignty, global unity, and open collaboration. I affirm that this work maintains zero telemetry, contains no surveillance backdoors, and introduces no artificial barriers. I build to bridge divides, expand access, and empower all of humanity."

3. Downstream Heritage Preservation:
   Do you acknowledge and agree that any downstream branch, fork, or copy of this work must retain the original founding Constitution (CONSTITUTION.md) in its entirety?

4. Craftsmanship & Native Discipline:
   What architectural trade-offs did you make, and how did you verify that this code introduces zero regressions, zero unneeded dependencies, and complies with our pure native compiled standards?
