Feature Request: Add macOS Support for Rockbox Zig

[tsirysndr]

Description

Currently, the Rockbox Zig project compiles and runs natively on Linux. The CLI client (rockbox) can be compiled on both Linux and macOS, but the daemon (rockboxd) only supports Linux.

Proposed Solution

• macOS: To enable macOS support, the CLI should detect the OS:
• Run both rockboxd (daemon) and rockbox natively on Linux.
• For macOS, keep the rockboxd daemon in a Docker container, while allowing the rockbox-cli client to run natively. The CLI will automatically spawn a Docker container to run the rockboxd daemon if it detects macOS.

Acceptance Criteria

1. CLI successfully detects the OS (Linux or macOS).
2. Both daemon and client run natively on Linux without additional configuration.
3. On macOS, the CLI launches the rockboxd daemon in a Docker container, while the client runs natively.

Additional Notes

This approach allows consistent functionality across both operating systems, preserving a native CLI experience on macOS while addressing the current limitations of cross-platform daemon support.
