#  Claude Code Mods — Windows installer
# ============================================================================
#  Run with:
#    irm https://raw.githubusercontent.com/hlsitechio/Claude-Code-Mods/main/setup.ps1 | iex
#
#  What this does, in order:
#    1. Shows the BETA warning + where to report bugs
#    2. Checks prerequisites (Node 20+, git, Claude Code CLI)
#    3. SCANS (read-only) for any existing Claude installs — and never
#       touches them. Your data is safe.
#    4. Asks WHERE to put this install (isolated directory)
#    5. Asks for consent before creating the local data backend
#    6. Clones + installs, then writes a one-click launcher
#
#  This script makes ZERO changes outside the install folder you choose and
#  its own data folder. It does not modify the registry, system PATH, or any
#  existing Claude / Claude Code / Claude Desktop installation.
