Implement Soroban Contract State Reader

[mijinummi]

🧠 Concept

Create a reusable service for reading Soroban contract state.

⚠️ Problem

Bridge integrations need contract state information for route validation and execution decisions.

📁 Implementation Scope

• src/soroban/state/
• src/soroban/contracts/
• tests/soroban/state/

✅ Requirements

• Read contract state through the Stellar RPC layer
• Support typed state responses
• Normalize returned values
• Handle missing state entries
• Cache safe read-only results where appropriate

🎯 Acceptance Criteria

• Contract state reader implemented
• State values normalized
• Missing entries handled safely
• RPC failures returned as structured errors
• Unit tests implemented

Hi maintainers,

I can tackle Implement Soroban Contract State Reader. Proposed implementation roadmap:

• Analysis: Inspect current behavior and edge cases in MDTechLabs/BridgeWise
• Core Implementation: Implement Implement Soroban Contract State Reader with thorough authorization verification and clean data structures.
• Quality Assurance: Ensure contract compiles cleanly and passes all cargo tests without warnings.

Looking forward to collaborating on this—please assign!
