Contributor guide

Research direction
Study the existing ABI implementations in pwndbg/lib/abi.py for architectures like x86, ARM, etc. to understand the pattern. Then implement classes for LoongArch64 and s390x following the same structure. For syscall names, check pwndbg/aglib/disasm/arch.py and add the syscall tables for these architectures. Refer to official ABI documentation or Linux kernel sources for syscall numbers and calling conventions.
