ARM64 (AArch64) backend for Rubix-lang

Technical Positioning
Expanding native compilation targets beyond x86-64 to include Apple Silicon and Raspberry Pi, enhancing platform compatibility and reach for a pure assembly systems language.
SaaS Insight & Market Implications
This issue addresses a critical market demand for multi-architecture support. Rubix-lang, currently x86-64 exclusive, faces significant limitations in modern development environments dominated by ARM64 platforms like Apple Silicon and Raspberry Pi. The inability to compile natively for these architectures restricts Rubix's adoption in embedded systems, mobile-adjacent development, and macOS ecosystems. Developers are forced to either use x86-64 emulation or abandon Rubix for projects requiring ARM64. Implementing an AArch64 backend directly expands Rubix's addressable market, enabling native performance and integration on prevalent hardware. This move is essential for Rubix to remain relevant and competitive as a systems language, mitigating a major platform lock-in pain point.

[ROADMAP]: Add ARM64 (AArch64) backend for Apple Silicon and Raspberry Pi

### Description
Rubix currently compiles exclusively to x86-64 machine instructions.

### Goal
Add an AArch64 code emission mode (`--target=arm64`):
- Map registers: `x0-x7` for parameters, `x8` for syscalls, `sp` and `fp` for stack.
- Emit ARM64 instructions: `ldr`, `str`, `add`, `sub`, `mul`, `sdiv`, `svc #0`.

### Target Files
- `src/codegen.s`
- `src/parser.s`

### Acceptance Criteria
- Rubix-compiled binaries run natively on Raspberry Pi (Linux ARM64) and Apple Silicon.
