Add a check_arch() guard that fails fast with actionable guidance when
setup runs on Apple Silicon under an Intel (x86_64) Python via Rosetta —
otherwise compiled deps (bcrypt, pydantic-core, …) load as the wrong
architecture and crash later with a cryptic "incompatible architecture"
import error. Also catch that specific error around the bcrypt import and
print rebuild steps.
Rebased onto current main: the start-macos.sh venv-Python changes that
were part of this branch are dropped, since they're already on main via
PR #978.

Serving a diffusion model auto-registered an image endpoint so it appeared in the model picker, but serving an LLM (llama.cpp/vLLM/SGLang/Ollama) did not — a downloaded-and-served model never showed up until the user manually ran /setup. Add _auto_register_llm_endpoint (text sibling of _auto_register_image_endpoint): parse the serve port (explicit --port, else Ollama 11434, else llama.cpp 8080), point an endpoint at http://host:port/v1, dedupe by base_url, and set supports_tools from --enable-auto-tool-choice. Wire it into /api/model/serve for any non-pip, non-diffusion serve.
start-macos.sh now skips Homebrew formulae that are already installed, so re-runs no longer re-hit Homebrew. tmux and llama.cpp are treated as optional: a failed install warns and continues instead of aborting the launch under set -e. Python stays required (it builds the venv).
