feat(macos): native install path via Homebrew

Browse Source 
install-macos.sh mirrors install.sh's split: every portable step - git pull,
venv, pip with the right overlay, npm build - stays in bin/sync.py, shared
with Linux and Windows. The script only does what sync.py cannot do for
itself on a bare Mac, which is install the Homebrew packages needed before a
Python exists to run sync.py with.

Two stages had to learn about darwin. ensure_exec_bits() keyed off
`os.name == "nt"`, which is false on macOS, so it ran the Linux path; and
requirements() had no darwin branch. linux_stage() now no-ops there, which is
what makes skipping the Ollama fetch correct rather than an omission:
bin/fetch-ollama.sh only ships a Linux x86-64 binary, and _ollama_bin() in
synapse/ollama_manager.py already prefers the bundled copy and falls back to
whatever `ollama` is on PATH. On macOS that is the brewed one, with Metal
acceleration and no flags needed.

The XFCE desktop branding is Linux-only and was already gated off macOS the
same way, so there is nothing to install for it here.

install-macos.sh joins the shell-parse list in bin/check.sh.
