refactor(contracts): remove deprecated AIPowerRental contract in favor of bounty system

- Delete AIPowerRental.sol (566 lines) - replaced by AgentBounty.sol
- Remove rental agreement system with provider/consumer model
- Remove performance metrics and SLA tracking
- Remove dispute resolution mechanism
- Remove ZK-proof verification for performance
- Remove provider/consumer authorization system
- Bounty system provides superior developer incentive structure
