feat: full auto-install chain for all platforms

- Wire ensure_claude_code() into cmd_update() — auto npm install if missing
- uclaude_install.sh: auto-install git, python3, curl via apt/dnf/yum/brew
- uclaude_update.bat: prereq checks with winget install suggestions
- uclaude_update.ps1: auto-install via winget (git, python, node)
- install_node(): macOS support via brew, RHEL/Fedora via rpm.nodesource
- Increased npm install timeout to 300s for slow connections
