feat: Reimplement core I/O and system information native methods with pure Java

- FastDataInput: DataInputStream wrapper replacing native binary I/O
- DNSLookup: InetAddress.getAllByName() replacing native gethostbyname()
- Restorer: Array.newInstance() replacing native makeArray()
- SystemInfo: Runtime/File APIs for disk, memory, CPU, platform info
- StatMemNode: Runtime APIs for memory status reporting
