Complete project rename from HARB/Harberg to KRAIKEN with KRK token symbol

- Renamed core contract from Harberg.sol to Kraiken.sol
- Updated token symbol from HARB to KRK
- Renamed TypeScript library from harb-lib to kraiken-lib
- Updated all contract imports and references across smart contracts
- Modified subgraph schema and source files for new naming
- Updated transaction bot dependencies and service references
- Fixed test files to use new contract and token names
- Updated documentation in CLAUDE.md and README.md
- Regenerated subgraph types and ABI files
- Added new deployment script (DeployScript2.sol)

All components compile successfully and tests pass.
Smart contracts: ✅ Compilation and tests pass
TypeScript library: ✅ Package renamed and configured
Subgraph: ✅ Code generation and build successful
Transaction bot: ✅ Dependencies updated
