fix(ollama): handle macOS tgz flat layout

macOS releases are a flat tgz (bare ollama binary + libggml dylibs +
mlx_metal dirs at the archive root), unlike Linux (bin/ollama +
lib/ollama/ hierarchy).

Detect macOS via uname -s, set pkg_src_cmd/pkg_dst_cmd to the
root-level binary, and move the full archive root into
~/.local/opt/ollama-vX.Y.Z/ in one pass.
