Implement Cross-Chain Bridge Protocol

[LaGodxy]

Implement Cross-Chain Bridge Protocol

Description: The current cross-chain support in the property token standard is incomplete. Implement a robust cross-chain bridge protocol that enables seamless property token transfers between Polkadot, Kusama, and Substrate parachains.

Acceptance Criteria:

• Implement secure token locking mechanism on source chain
• Develop mint/burn or lock/unlock logic for destination chains
• Add bridge operator management with multi-signature validation
• Create bridge status monitoring and error recovery
• Implement cross-chain metadata preservation and synchronization
• Add comprehensive integration tests for bridge scenarios
• Include gas optimization for cross-chain operations
• Provide bridge transaction hash verification system

Files to modify:

• contracts/property-token/src/lib.rs - Complete bridge implementation
• contracts/traits/src/lib.rs - Add bridge traits
• tests/integration_property_token.rs - Add bridge tests
• Create new contracts/bridge/ module for dedicated bridge logic
