JingMatrix e7d7b21daa Fix ARM ptrace compatibility and improve remote call safety (#94)
- Implement fallbacks to `PTRACE_GETREGS` and `PTRACE_SETREGS` for 32-bit ARM (`__arm__`). Some kernels return `EIO` or `EINVAL` when attempting to access `NT_PRSTATUS` via `PTRACE_GETREGSET`/`PTRACE_SETREGSET`.

- Update `transfer_fd_to_remote` to use `libc_return_addr` instead of `0` as the return address during the `recvmsg` split-call. This ensures the remote process stops predictably at a known non-executable location rather than relying on a potentially unsafe jump to `0x0`.

- Clarify comments regarding i386 argument passing in `utils.cpp`. Correctly note that a linear `write_proc` starting at the new SP matches the `cdecl` Right-to-Left memory layout (since stacks grow downwards while memory writes move upwards), removing the suggestion that arguments needed reversing.

JingMatrix 0c1937bd3e Implement shared library injection via ptrace
There are still many functions in the header `utils.hpp` not implemented yet, which are however not needed for our purpose.
