main shipped v1.0.0 with prebuilt Windows binaries but no docs on main explaining what the .exe is or how to run it (#450) — the quickstart lived only on dev. Bring docs/quickstart.md to main and add a Windows-prebuilt pointer to the README's Get started section, so users on the default branch find the steps. Docs-only.
