Build Soroban Contract State Snapshot and Restore Capability for Testnet Debugging

[temma02]

Description

Implement the ability to snapshot and restore Soroban contract state on testnet, enabling developers to debug deployed contracts by capturing and reproducing specific state configurations.

Requirements and Context

• Debugging: Testnet contract state must be capturable and restorable
• Testing: Test snapshot and restore round-trip
• Documentation: Document the snapshot/restore workflow

Suggested Execution

Branch: feat/issue-087-soroban-state-snapshot-restore

Implement Changes

• Add contract state snapshot logic to the Stellar package (testnet only)
• Serialize contract storage entries into a portable snapshot format
• Implement restore logic that reapplies a snapshot to a testnet contract
• Guard snapshot/restore operations to testnet only

Test and Commit

• Test snapshot capture and restore round-trip
• Test that snapshot/restore is rejected on mainnet
• Document the snapshot/restore workflow

Example Commit Message

feat(soroban): add contract state snapshot and restore for testnet debugging

- Serialize contract storage into portable snapshots
- Implement restore to reapply snapshots
- Guard operations to testnet only

Guidelines

• Restrict snapshot/restore strictly to testnet
• Use a portable, versioned snapshot format
• Never allow restore on mainnet
