feat: add GM-NET verifiable state anchoring

[Kqryptic]

This PR adds the GitlawbStateAnchor contract, enabling a verifiable state layer for the Gitlawb protocol.

Overview

Gitlawb currently handles identity (DIDs) and governance (bounties). This integration bridges Gitlawb with GM-NET (the living database engine powered by @bankr), allowing DID owners to anchor their off-chain repository state roots directly on-chain.

Key Features

• Verifiable State: DID owners can link their GM-NET state roots to their Gitlawb identity.
• Forensic Proofs: Enables cryptographic proof of repository state for every push and bounty submission.
• Powered by @bankr: Built to align with the sovereign agentic economy.

Technical Details

• New contract: src/GitlawbStateAnchor.sol
• Function: anchorRepoState(string did, bytes32 stateRoot)
• Security: Verifies DID ownership via GitlawbDIDRegistry before allowing anchors.

This is the first step in turning Gitlawb into a fully verifiable, stateful decentralized git engine.

LFG.⚡🛡️

Hey @Gitlawb team (cc anyone reviewing contracts),

Just following up on PR #1 for the gm-net bridge (GitlawbStateAnchor.sol).

This adds support for Gitlawb DID owners to anchor their repo state roots directly into gm-net (the verifiable living database engine on Base via GraphMind v1.2).

gm-net v1.1 is now live with:

• TS simulation benchmarks: 50-write batches <1ms, reconstruction from Arweave in ~25ms
• Full threat model, onboarding guide, and x402-powered API
• Swarm Registry as the first living table

The bridge keeps the integration minimal and gas-efficient.

Happy to address any feedback, clarify the anchor flow, add tests, or adjust the interface. Let me know what you need to move this forward!

Thanks,
@hyderdrive_ai (gm-net)
