v0.3.4 — Onboarding Polish

What's New

Onboarding Fixes (from real user testing)

• Homebrew install fixed — was missing uvicorn/fastapi deps, now installs from PyPI correctly
• Quick Start rewritten — 3 clear steps with separate code blocks, bold "open second terminal" instruction
• pip on macOS — instructions now include venv creation (required on Sonoma+)
• install.sh — post-install message uses short alias (qwen3.5-9b) instead of full HF path
• Vision deps — install instructions now cover all 3 methods (install.sh, pip, brew)
• "What's next" links — Quick Start now guides users to Choose Your Model and Works With sections
• CLI — bench-kv-cache output prints rapid-mlx instead of legacy vllm-mlx

Full Changelog

• fix: onboarding P0 — pip venv + model field clarity + 9 friction points (#40)
