feat: Prepare for STARK Proof Verification

[GoSTEAN]

Description

Starknet's STARK proofs enable scalable off-chain verification, ideal for complex checks like inactivity periods. While not fully supported yet, preparing the contract for STARK proof integration will future-proof it for verification tasks.

Tasks

• Add a placeholder verify_claim_with_proof function to accept STARK proofs.
• Use Poseidon hashing to prepare data for future STARK proofs.
• Monitor Starknet's roadmap for STARK proof support and update logic accordingly.
• Document the planned STARK proof integration.

Acceptance Criteria

• verify_claim_with_proof function is implemented as a placeholder with Poseidon hashing.
• Claim data is formatted for future STARK proof compatibility.
• Unit tests mock STARK proof verification and validate placeholder logic.
• Documentation outlines the planned STARK proof integration and roadmap dependencies.
• Issue is updated when Starknet's STARK proof support is available.
