CCF v1.7.1

[1.7.1] — 2026-06-17

Added

• Windows one-click install: install.ps1 rewritten into a full bootstrap — detects winget
  (or Chocolatey), auto-installs every missing requirement (Git for Windows → bash+curl, jq,
  Python 3), refreshes PATH in-session so tools work without a reboot, verifies, installs CCF,
  and launches the setup wizard. -Yes for fully unattended.
• install-windows.bat — double-click installer (handles execution policy, pauses on output).
• docs/WINDOWS.md — Windows quickstart + troubleshooting table (winget/App Installer,
  execution policy, PATH refresh, proxy, WSL fallback, manual install).
