Add AKF — The AI Native File Format instructions

[HMAKT99]

Adds instructions for AKF (Agent Knowledge Format) — the AI native file format.

What it does: Instructs Copilot to stamp every AI-generated file with trust metadata — trust scores, source provenance, and compliance data. Think EXIF for AI.

Why it's useful:

• Every file Copilot creates/modifies gets stamped with provenance (~15 tokens of JSON)
• Metadata embeds natively into 20+ formats (DOCX, PDF, images, code) — no sidecars
• One-command compliance audit (EU AI Act, SOX, HIPAA)
• akf read <file> before modifying shows existing trust context

Install: pip install akf

It looks like you've incorrectly branched from the main branch not staged, and as a result all the materialised plugins are included in this PR.

You can attempt to fix this with a rebase:

git fetch origin staged
git rebase --onto origin/staged origin/main <branch name>
git push --force-with-lease

If that does not resolve it, you can run npm run plugin:clean which will delete the materialised plugins and you can commit that change.
